Admin can manually change 'form' for user

[alexrollin]

Currently there is no way for an admin to 'switch' a user as having registered from form 1 to say, form 3.
Enable admins to 'switch the user over' so they can have users seeing the correct tabset.

Switching is not possible unless they register again on the site with the correct form or delete their account and register again on the site. Because not all forms will have the same fields so if the user switch form then new form fields might be blank and old form fields may be of no use.
Need inputs from @Stiofan

We will need a way for them to stitch, even if at the time they need to fill out more info. Let me know your solution.
