Please let the "Completionist Showcase" more than two.

Hope that "Completionist Showcase" can be more than two.
In order to show that we have obtained full achievements in our favorite games, we buy games, spend a lot of time, and finally spend points to show it. This should be a win-win-win situation. (steam, game company, player), thank you.

You already can do this; you just have to upgrade it with steam points:

It's the "Completionist" upgrade here.

EDIT: Oh right, you mean a third whole showcase. My bad. Yeah that's as much as you get I'm afraid.

Valve recently patched out the method to get 3 of a single showcase. Take what you will from that.
