is it possible to create an item that allows me to command entities?

To move it to a block

I think you could spawn a dummy entity

And make it follow it once you interact with the item

Hmm

But what about going to another entity?

I guess I could think about the tags a bit more

[stark oar]

Use tags or scoreboard or dummy components

Or effects

[jolly elbow]

Ok I'll see if I can do it

Good luck
