How to stack different versions of the games?

[tiualex]

Hello, recently I added no-intro set for commodore amiga into my library. But I noticed that there are different versions of some games in the set, for example:
Jaws (Europe).zip

Jaws (Europe) (Alt 1).zip

or

KGB (Europe).zip

KGB (France).zip

These versions are displayed with the same covers and look like duplicates in my library. On other platforms I didn't have such problems. Different versions simply stacked and were available for launch if you right-clicked on the cover and selected the version. So my question is, is there a way to automatically stack these different versions of the games into one with the ability to select the version in the menu?

When importing make sure the "Combine similar ROMs" (or something similar, the only one that says combine lol) is checked and this will be done automatically. If you don't have this and later want to combine games just select each game you want to stack together, then right click and select "Combine Games". It'll ask you in a pop up which should be the primary, just pick the one you want then press ok.
