One of the Show Message Action options is "Provide Yes/No option to user? 'Ok' assigns True. 'Cancel' assigns False.". When the message window appears, the two buttons are 'Ok' and 'Cancel'.
Would it be difficult for the Method team to add the ability to change the captions of those two buttons in the action setup? For example, I have a situation in which I would like the buttons to read 'Use Blank' and 'Use Template'. I think allowing the buttons to better reflect the message would be an improvement.
