Ability to only post one listing


After speaking in the live chat, I was asked to start a thread in the forums (I hope I am in the right area) to see if the developers could make this possible.

Using the directory plugin, I would like the ability for users to only to be able to create 1 listing, and not have the option to see other peoples directory listings in the back end (although they can not edit them right now, they can still see that they are there.)

I was also wondering if there is a specific availability calendar that could be used with the directory listing? I am hoping that the availability calendars could be separate for each individual listing.

Is this possible? I look forward to hearing back from the community.
