QoL Request: Allow us to take out individual items from Mogstation letters

The new adventurer supply kits on the mogstation are a fantastic addition to the store both for newer players but also for people with a lot of alts like myself!

That being said, an issue I've run into is that because of how the current letter and item system works, it's really irksome to be able to receive the items from them if you already own certain things (especially the Menphina earring in this case).
With that item you can work around it a bit by moving it into another storage space like an Armoire, but it still seems very impractical that we can't take out the individual items from a mogstation letter like that one when if I recall correctly we can do it just fine with regular letters from friends (something I didn't really think about much until trying to open this specific kit).
Ultimately it doesn't matter too much, but I saw others also had this problem as well in the comments of a tweet about the kits and figured it wouldn't hurt to ask here.
