Claiming chests as different characters

Before the New Ui was rolled out there used to be a mod called UI Improvements for the old/legacy UI. This mod has since been adandoned, made outdated and is now unsanctioned. One of the features of this old mod was being able to open chests for different characters to the one you were currently playing/had selected. Even if the character you wanted to open the chests for was being occupied by another player you could still open a chest for that character. I initially wondered why this feature was not rolled out with the New UI as it’s a great feature to have as I don’t like asking people to change character just to open a few chests. I feel like it could be implimented through the inventory screen just as you can alter different character and class builds without actually switching.
