Does anybody know if instead of Era-Specific soundtracks I could make Civ-Specific soundtracks?

Example Gladiator Soundtrack - Roman , I know manually I could switch it but what about auto like era in the game.

No one have not done this before, Civ-specific music is hard to do, and it will take a lot of time trying to put in 5 songs on each era for each civ as well.
