Adding a third listing type

Hello!

I see that there are two listing types: Free and Premium.
My idea would be to insert an intermediate type (Standard) which would not allow for the lead form to show (therefore, only Premium users would be able to have lead captures).
Is there a way this can be done?

Note: I am not allowing users to add their listing (I've removed the link). Only I am able to do that.

Thank you in advance,

Henrique

 

I have found an alternative situation.

Thanks anyway
