That would end up being more difficult than simply right-clicking the check and duplicating it.
So much for duplication... how about automatically generating and inserting a check? For example, I have 2 million screens each with 500 values I know are currently correct but need to verify don't change after each release. We have a script that goes through each screen as it is but we need a check for each screen, as each screen is unique. I don't want to manually go through and INSERT>CHECK>CONTENT for each screen.
I want to write a script to look at the page and automatically insert a new content check for that screen in the TP database.
