already in development but questions raised

Hi guys.

I hope this is allowed and i apologize in advance if it is not.

I have a plugin developer looking into customizing the pro sites plugin to work the way i need it to work and I am after some information/ advice.

The plugin as it stands does everything i need it to do except for 1 thing, I am looking to be able to offer each membership the ability to have a pre determined amount of sub domains available to the user upon registration, for example, level 1 would offer only 1 subdomain (as it does already), level 2 would offer 1 subdomain also, BUT from level 3 through level 5, i want to be able to give the user the ability to choose additional sub domains without having to re purchase.

What i mean is that if you registered at level 3, you would choose your first subdomain and if you wanted more (up to 5) you can go back through the process and register additional domains WITHOUT having to make additional purchases in order to get the additional sub domains.

I have seen some sites that are able to offer unlimited sub domains (not sure what membership plugin is used) but i want to offer a set amount based on the level they join at without having to repurchase every time and have a monthly subscription for EACH subdomain.

I understand that I will no doubt be told to ask in the “Find a Pro” section of this site (which i HAVE done) and I have a member from the “Find a Pro” section working on it but I have been informed that “It may be possible and it may not be possible” so I was hoping one of the original developers or someone who has already had the plugin customized may be able to point me in the right direction as to whether this can in fact be done without causing issues for the other processes the plugin runs.

Thanks in advance
