Pro sites free level subscrption

Hello guys,

What i want to do?

I want a free level where users are able to use some plugins and themes.

But I realize that there is no Free subscription level in pro sites except from the default free level provided by pro sites.

The default free level does not provide to users any plugins or themes, am i right?

Also, there is a free trial level where users can use a premium level for couple of days or weeks but i do not want to use it.
