Multi-Mystery Part Madness

Hey PMU! I recently ran Tanren Chambers to help some other users get Mystery Parts. Now that I have two, I thought I could make use of one each for two legends for each, saving me money greatly since I don’t really plan on using more then four Legendaries. However, I can only use a Mystery Part if I have only one in my inventory!
Mystery Part Use with multiple parts

Is there perhaps a way of having a Mystery Part show what’s in it’s contents so I can at least ensure I’m taking the right one with me to dungeons? I was sure having two would be fine, since PMU won’t allow you to use a Mystery Part if you have a Legend in your party already, so this seems more irksome then anything knowing I can’t do that. Any ideas?

Technically u can just try to use one in pebble cave and try to remember it off that but if they added a way to see it in the items description perhaps that’d be a real neat change :)
