I'm making an anchor program where I would like to make a user ID easily retrievable with their Pk, sequential ID or username. one way I thought is to make a PK link account (in case the seed for the ID account required the PK), which could be made from seq ID seeds or username seeds. however, this is one more hop than I'd like. Can an account be made to point to another in an easy way?

(like your own ID or username)
