A couple of years ago we were able to place here not only games but DLCs too.
But the Game Collector Showcase no longer supports adding DLCs to it.
I suggest to bring this feature back or add a new profile showcase for DLCs.
Why?

1. Some DLCs can be better than other games. I want to be able to show them on my profile.

2. It will give more opportunities for profile customizing due to more variable game (DLCs) covers.
I'll give you an example. I would prefer to place the Cyberpunk 2077 phantom liberty cover in my showcase because of its raspberry color, which looks more harmonious than the original yellow Cyberpunk 2077.
