Suggesting and owner attribute, such as dropitem{i=DIAMOND;owner=<target.uuid>} @PIR{r=5;limit=1;sort=nearest} to assign a player UUID to the item being dropped as the owner NBT of an item entity the "dropping player" - this causes the drop to prioritize being picked up by its owner UUID rather than other players for a moment, and gives a compatible record of "who dropped this" that can be utilized in other ways.
Additionally, the set/get owner mechanics of Mythic being compatible with this field of item entities would further expand this feature usability.
