Can we get a search selection for 'Unknown' in guild stores please?

I've always missed this feature when I was missing a few pages of a certain motif.
You can search for all the pages of a motif, or just one specific one, but not only just the ones you have not learned yet.
Same for consumable and furniture recipes. I just want to check if they have something I have not learned yet.

Now with the sticker book coming, I'm expecting again to scroll through pages full of items I already learned, while
I'm only looking for Unknown items.
