Hello,
I am not quite sure I fully understand your question here. Would you like to have a different copy of the AIP file after everytime you change something?
If so, I'm afraid that it's not quite possible, at least through our support.
You could enable AutoRecovery, but I'm not 100% sure that is what you are looking after.
Unreversible changes should create a backup copy of your project (e.g. building in a newer version of Advanced Installer). This option should be enabled by default and you can find it here:

Hope this helps!
