Using a WiX Selection Tree control, when I select Feature 1, I want Feature 2 to be selected automatically

Question

I have three features in a Selection Tree control. I would like Feature 2 and 3 to be independently selected and installed but if Feature 1 is selected to be installed I want Feature 2 to be automatically selected since Feature 1 depends on it. When my Selection Tree is displayed I see:

[-] All Features
    [x] Feature 1 (requires Feature 2)
    [x] Feature 2        
    [x] Feature 3

Where [-] represents the icon for "Will be installed on local hard drive" and [x] represents the icon for "Entire feature will be unavailable".

When I select Feature 1 to be installed I see:

[-] All Features
    [-] Feature 1 (requires Feature 2)
    [x] Feature 2
    [x] Feature 3

But when I select Feature 1, I want Feature 2 to be selected automatically so it would look like this:

[-] All Features
    [-] Feature 1 (requires Feature 2)
    [-] Feature 2
    [x] Feature 3

I don't want Feature 3 to be automatically selected since it is not required by Feature 1. Is there a way to do this? This seems like a simple problem but I could not find any documentation or examples on how to do this. I have tried to use a condition within Feature2 like the following but the condition never gets tested since only Feature 1 was selected:

<Feature Id="ProductFeature" Title="All Features" Display="expand" Level="1">
  <Feature Id="Feature1" ConfigurableDirectory="APPLICATIONFOLDER"
           Title="Feature 1 (requires Feature 2)" Level="2">
    <ComponentRef Id="file1.txt" />
  </Feature>
  <Feature Id="Feature2" ConfigurableDirectory="APPLICATIONFOLDER"
           Title="Feature 2" Level="2">
    <ComponentRef Id="file2.txt" />
    <Condition Level="1">MsiSelectionTreeSelectedFeature="Feature1"</Condition>
  </Feature>
  <Feature Id="Feature3" ConfigurableDirectory="APPLICATIONFOLDER"
           Title="Feature 3" Level="2">
    <ComponentRef Id="file3.txt" />
  </Feature>
</Feature>

If only Feature 1 is selected, is there a way to "tell it" to set the Level attribute of Feature2 to 1 so that Feature 2 in the Selection Tree displays the icon showing it will be installed also? If trying to set the Level attribute of Feature2 is not the right approach, is there another method I can use to accomplish the behavior I desire?

Can you try putting a variable for level, that way you can use a custom action when you click the next button for example to check if feature 1 is selected then update feature 2 variable to the level you require? — Sjharrison, Jun 30 '15 at 13:31
Using a variable with a custom action is a great idea but I wanted feature 2 to be shown as selected in the UI before the next button is clicked. I ended up creating my own dialog using my own checkboxes which gives me the ability to do what I want since it gives me total control of how the checkboxes appear before the next button is clicked. — Gary, Jul 25 '15 at 17:31
