integration with osproperty 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 .

Hi Alex

I will move this question to the OS Property forum category so that the developer of OS Property can answer this question .
