Customizing Auto-Correct in a form

This is a twist on the other questions here on how to get rid of auto correct.
I want to retain a custom auto-correct library in a form I am creating in
Excel. My problem is I create the auto-complete (auto-correct) in the form
and it works fine. But when users get the form it no longer works. In
autotext there is a setting to apply autotext only to the form but I can not
find a similar setting in Autocorrect.
Is there VBA to do this?

Thanks
Jack
