Change MES Tab Stops

What is the trick to make changes to the Tab Stop setting and Tab Index order in the MES screens?

In Epicor ERP 10.1.600.9 MES, I’ve created a customized “Start Production Activity” screen (from Base). I set some of the un-used fields to be Visible = False, and then I want to change the Tab Index order and the TabStop value (from False to True) for some of the fields. Each time I make the change, the TabStop value gets changed back to False and some of the fields I’ve set to Visible = False go back to being Visible = True.

What is the trick to modifying the MES screens? (Esp. Tab Order and TabStop values?) I see there is an old link on this topic where the person said they gave-up. Has anyone had any success with this?

It’s a bit tricky. The tab stops are hardcoded based on EpiBinding.

Option 1: Break the epibinding of the controls (aka handle your own entry into the fields)
Option 2: Hijack the form by brute forcing their event handler through unsanctioned methods

Neither option is great.

Edit - another funky way might work based on the order of operations. OnEnter - remove the EpiBinding from the control, store it, then on OnLeave add the EpiBinding back
