Mythic+ Comp Builder website?

I've researched a bit on google for a website that would allow me to "build" a Mythic+ comp and show me what my comp has and doesnt have (battle res, bloodlust, raid buff, cc and types of cc, etc), but sadly I only found tier list websites.

I dont want to (necessarily) follow a tierlist. I want a tool that allows me to cook it myself. Does it exist and if not, perhaps it should...
