Please let the Gallery show us missing Base Game items like with Addons

I've  played the Sims since 2001 with some gap years as I didn't have time enough back then, but still coming back. And I has such a gap between 2015 - 2017ish for the Sims 4. And I missed some time limited stuff unfortunately. The Gallery tells me that I miss objects alright and I like that basically. But it only does so for Addon stuff. If items are Base Game, like thos earlier mentioned limited items, the Gallery only shows a green icon on the upper left corner but I am unable to see what exactly I am missing, when looking through "view used items/objects" in the Gallery post.

Please consider making this option available for missing Base Game stuff so people can see if a lot/aim is missing a limited item and can get straight to substitute it instead of guessing what's missing. Especially that there is an abandoned fallback system for BB and none at all for CAS. It's just frustrating at this point.

I fortunately do have allmost all limited items aquired when the preorder stuff was introduced with COL and later on the free event items. But I do feel real bad about all newer players never getting a chance to aquire older limited items and also never know what exactly is missing, although the Gallery is capable off showing used/missing items.
