Feature change request within the chest

Dear blizzard,

I would love to see a quality of life feature which I will explain below.
Lets say I have multiple chars and I am using the armory for each of those chars to register my multiple builds. Now I want to clean up my chest because I am a damn messy. To keep track on which item is used in the armory is really hard especially when your chest is totally full.
Can we get a feature that somehow highlights every item in chest that is registered in the armory please?
That would be a huge quality of life improvement.

Merry christmas
Best regards
