Player and Mob State Prefix

There are a lot of prefixes for the @e[], but there is not a player state. What I mean is that it would be nice to have another prefix for the @e[] that would target player states like sprinting, crouching, walking, etc. Not only players but any entity as well.

With this prefix existing, it would go perfectly with the playanimation command.

I imagine that the command would look something like:

/tp @e[state = {animation.filepath}] @s

or

/tp @e[animation = {animation.filepath}] @s

or

/tp @e[animationstate = {animation.filepath}] @s

With this being added, it would help me with a horror game I am working on.

Thank you very much for listening:)
