Stacking still has some issues

It's been a while, but I've noticed that stacking still has some issues. One being that we can't search for certain games while adding to stacks even if they were reviewed on GS and, at times, DO have pages. Three examples being: BloodRayne 2 (which I want to add to my PS2 stack), Tekken Tag Tournament 2 (which I want to add to my Wii U collection), and The Wonderful 101 (same as Tekken).

Also, even when a game I can't search for still has a page, (ex: BloodRayne 2 as I can still access that from my games I want stack), is there a possible way to add a drop down tab to put it in the stack(s) you want?

Something to bring up if it hasn't already. :)

Thanks for your suggestions! At the time we are not actively working on upgrading the stacks system but we will keep this in mind when we improve stacks.

I'm facing the same issue, albeit with a different game.

When i type "dark souls" to the search box in order to add it to one of my stacks the list only displays Dark Souls II & III, among other titles, but not the first one in the series.

Is this a bug then?
