Swap page improvement - upgrading your collection

(Forgive me if this is already an idea here):
Would it be possible to add a block to show what conditions of coins I already own when compared to another user’s swap list? For example, this user has XF coins that I already have (the check mark ✅ on 1994 and 1995 25 centavos). If we could display not just the check mark, but also the condition of that year I already own (F for example) I might add them to the swap to upgrade my collection.

Ideally, I think it would look something like this:

Or perhaps by hovering over the ✔️ it would reveal the condition in your collection

This could help to improve collections.
I'd love it!
