Wild Card in Control from Description

Hello!

I am trying to target a text box in an application. Auto-configure seems to target the window correctly, but changing the instance of the application seems to change a number in the target, breaking the script. Any way to replace the number in the following with a wild card? If not, is there a workaround? 

FindChildCardinal(“Transparent Windows Client”,1)

FindChildCardinal(“Transparent Windows Client”,2)

FindChildCardinal(“Transparent Windows Client”,3)

Thank you!
