I appreciate the suggestion, though we actually had a pretty similar idea show up back in September, to which I’ve just responded not too long ago. That idea revolved more around storing the items rather than utilizing them though.
Basically my response to that thread amounted to “sounds like a neat idea, but as is we tend to just run our favorite mons anyways and ignore other fam items, and the remaining appeal to those who just like collecting things doesn’t feel like enough of a niche to budget the development time to it (compared to something else that would affect more/all players)”.
Though I wouldn’t be opposed to getting development time on an update to help make these items easier to find in storage by category separation. An entirely new inventory/storage system isn’t in the cards right now though.
