No, that's not going to work. But you can hide that button and just create yours.
I always hate to be "that guy", but I fear using a STE for this sort of activity is not the best approach. What you describe (creating a record where field choices are interdependent) is closer to going through a wizard than mass-editing raw SQL rows.
It would probably be better to have a dedicated pop-up with (at least) the basic fields a user has to enter when creating records, which you can control more precisely. You can then provide a STE for reviewing or mass-updating records afterwards, if necessary.
Hi Jack
That sounds like a possible solution, however, I'm not sure how I would get a pop dialogue when creating a row? Is it achieved by setting the 'Selection Changed User Interface Action' below to Open Dialog?
Assuming we are talking about a button (which is what i had in mind, something like "Create New Entity"), yes - and note that there are many "Open Dialog" options to help you manage the relevant popup. You'll also have to set the "Dashboard to Open in Dialog" property to point to the dashboard that will be used in the popup.
I was hoping to be able to use the add new record button?
