Adding a "Home" Location for the Allay

I think one addition to the Allay that could make it go from cool to top-tier is the addition of a way to set its "home" location that it will return to after dropping off all its items. The idea that sparked this suggestion was thinking about an Allay mail system for either single or multiplayer. Essentially, the player could make a hub area with a bunch of Allay each tuned to a specific noteblock. The player could then throw a shulker to an Allay and send it to deposit to a location and have it come back to the hub.
