"Add plane" unclear?

I’ve noticed that new users routinely have trouble identifying “Add plane” as the way to specify a net for a polygon. I wonder if something like “Assign net for plane” or “Specify net for plane” or “Define plane net” would be more explicit or helpful.

How about “Assing plane”?

Yes, “Assign plane” would be an improvement to my ears.

Thanks! Hope this helps.
