Merge request assignee permission description in assign user dropdown

Description

I was searching a bit over issues, but none of the keywords put the suggestion on top. Anyway, I am working in a lot of groups environment with a lot of projects. That comes with a strict merge flow where only certain people have certain access rights on certain projects/groups. We do assign first reviewer to be the one most experienced with merge request topic (for upvoting). After that I would like to change assign to a "merge" reviewer (one with Accept privileges), but I have hard time figuring out who all has permission to do so in certain project/group (protected branches).

Proposal

List permission level (Guest, Developer, Master ...)next to the name of the Assigned user in drop down menu. Or color them differently where one that can accept the merge request are bolded, while others are in normal font or slightly grayed out. GitLab can figure who can do it, as it displays exclamation mark sign next to user but that is after you assign him/her.
