Question about built in revision system and BU Versions

[ChongoShaun]

I have an interesting use case that came up and I'm wondering if something is even possible with BU Versions.

When the user creates a clone page and makes edits, the first 'submit for approval' has no way to tell the difference between the very first version vs the new submitted version. However, if the user submits for approval again after another change, the built in revision system kicks in and you can now view diff's between both submissions. Is there any way to add the ability for the built in revision system to kick in on the very first 'submit for approval' ? this way administrators of the site can see the difference between the original version and the new copy before approving it and moving it live.
