Please make an UNDO feature for the Network Security Policy instead of Cancel

I just accidentally deleted a rule when I wanted to create a new one and I have no idea what it was. It was the first rule. Why not have an undo option so I can get a back a rule accidentally deleted if I make multiple changes at once?

I made a second post similar to this one, but instead of a an undo option, there should definitely be a enable/disable rule checkbox for each rule. There is NO question about it.

There is a topic in the Wishlist for this, if you would like to post in it;msg299814#msg299814
