Yes, it's possible to do via Studio->Forms->Market app, 5 diplsay area. Choose the necessary form there and click the link near with the title like "10 fields". In the appeared list you may see the "Visible for" column which shows the levels having access to this field. If you click it then you may edit the permissions lists who will see this field.
There is no paid level on this list (but you may make Premium like wanted). You need to create a new one via Studio->Permission App and then make it paid via Paid levels App. And the work with this new level in Visibility filter.
