Hi @Flyingfishnm ,
1\ No.
2\ If you want to create variables automatically, please try the following ways.
(1) Use app's OnStart property. Automatically create a variable when the app is opened
For example: you could use this formula on OnStart property
Set(Thevar,"Test")
(2) Use screen's OnVisible property.Automatically create variables when a specific screen is visible.
For example: you could use this formula on OnVisible property
Set(Thevar,"Test")
3\ You could create a collection in powerapps.
For example: Add a button control and set its onselect property to:
ClearCollect(Col,{Column1:"A",Column2:"B"},{Column1:"C",Column2:"D"})

Of course, you could also use onstart property or onvisible property instead of button control's onselect property.
