Choose Which Role gives you you username colour

So I can't seem to find if their are any similar post on this topic, thus I am posting it as its own thing. I am in a number of servers where I have multiple roles, however I have always found it weird that you can't pick what role you want to provide you the colour of your name within a server.

For example I am in a server where I currently have 4 roles, each with its own unique colour, however I am unable to pick which role I want to have the colour of my name to represent in that server.

Just thought it would be a nice thing to have, since I've talked to a number of people from multiple servers who've wished such a thing was available.
