The only way I know how to do this is to use default values that will pass the required check or disable/enable the required flag programmatically as needed.

I came up with a possible solution, though I don't love it. 1. Make sure none of the fields are required. 2. Added a required droplist with the options "Draft" and "Final" (or whatever terminology you want) 3. Use frm_validate_field_entry to check the value of the droplist in step #2 and if it's "Final", throw an error for each field that you want to be required and doesn't have a value. In my case, I'm going to an absolute crapload of fields to put in that filter, but, in theory, it'll address the problem. Can I say how much I don't like it though?

Update: I dove a little deeper and came up with a much better solution and wrote a tutorial for it.
