Questions creating a custom Polymorph or Wild Shape adjustment

[TheRello]

My DM has given my character a custom item that allows me to change other creatures into different races, animals, or monsters that I have unlocked for a few minutes at a time. I have been playing around in the Hero Lab Editor to create this and I have most of it figured out. I have made a copy of the beast shape ability in the adjustment section and then removed the Eval Scripts which now lets me select all monsters and races.

But I am having the following issues.
1. I would like to find a way for it to also change the ability scores to that of the selected option if there are any.
2. I would also like for it to be able to put everything back to the way it was once I turn the adjustment off. Currently, I have to delete the adjustment to get this to correct itself.

Anything anyone can do to help would be greatly appreciated. Even if it is explaining or leading me to some guides on where I can code it myself. I have been playing with this and googling anything and everything and I have had no luck. Thank you in advance!
