Throttling the Commit/Revert data entry dialog

I love the FMP7 feature of layouts that do not immediately save, but hate that it prompts you every time you click outside a date entry box, instead of just when you try to leave the record/close the window.

Basically, when a user is about to leave a record, I need to offer three options: Save, Revert, and Save with Version Update. The last option has some housekeeping routines attached, and rely on a user choice to know which to run.

Easy enough to script, but the problem is that REVERT only works when the layout is set to *not* save immediately, but then the problem is that whenever the user clicks outside of a data entry box, Filemaker automatically offers up its own "Save/Cancel" dialog box.

This is confusing for a user.

How can I offer the 3 save features I need, but at the same time halt the 'native' save dialog?

My plan B at the moment is that I set the layout to save automatically (which will then negate the revert function once anyone clicks outside of a data entry field), and try to program the "revert" function manually (save record before edit for reversion).

I imagine one of you knowledgeable pros had to implement such a 'revert' feature in a pre-FMP7 (when there was no commit/revert!). So my fall back question
