How can I add a command to the Visual Studio toolbar to switch between source control plug ins?

Question

I'm working with several different solutions, some of which use tfs and some which use svn. I would like to add a button in the toolbar to switch between providers instead of having to go through the "options" menu. How can this be done? Note: source control switcher doesn't work with VS2013

Answer 1

There does not seem to be any direct way to add the command "Current source control plugin" to the toolbar, via toolbar customization.

Maybe a Visual studio extension could be written for this.
