integration with osmembership needs better rules

I have membership pro + osproperty, i need that a subscriber be able to upload ilimited properties. but is necessary to set a number of properties.
exemple:

plan A: ilimited normal properties and x featured properties.

but when user buy a plan, the previuos one is cancelled. This prevents the 2 plans be combined to get this target .

Thank you for your suggestion, we will think about it.
