Hi @BrianHFASPS ,
Do you want to utilize one button across multiple screens via Select() function?
If you want to utilize one button across multiple screens via Select() function, I afraid that there is no way to achieve your needs. The Select function can't cross the boundaries of container controls, e.g. Gallery, Screen, Form, etc.
More details about the limits on Select function, please check the following article:

According to the needs that you mentioned, I think the OnVisible property could achieve your needs. In the first screen, add a Navigate button, set the OnSelect property to following:
Navigate(Screen2, ScreenTransition.None, {Param1: Value1})
Within the second screen (Screen2), set the OnVisible property to following:
Back()
If you want to navigate back after specific seconds (e.g. 2 seconds), I think the Timer control could achieve your needs. Please consider add a Timer control in your second screen, set the Duration property to following:
2000
set the AutoStart property to following:
false
set the OnTimerEnd property to following:
Back()
Please consider take a try with above solution, then check if the issue is solved.
Best regards,
