Naming files in Gigapixel

When saving a picturs in Photo AI, I can choose, if the applied filter is used, of it I shall overwrite the original file, etc.
When klicking “Apply” in Gigapixel AI it overwrites the original file without asking.
I fo not likle that and I have not found, if or where I can change that it saves the edited picture to a new file or save and add an appendix to the original file name.

Any suggestions?
