In VSTS it is possible to create variables per build definition as per the Microsoft documentation
https://www.visualstudio.com/en-us/docs/build/define/variables
Is it possible to define global variables that I can use across multiple build definitions?
Scenario:
I have a variable 'MyPassword' that is used in multiple definitions. If I want to change the value of 'MyPassword' I have to do it in each build definition rather than just in one global variable.
