Uploading users and bulk adding subscriptions

I’m working with the Membership plugin, but want to use it in a slightly different way. What I’m trying to build isn’t content an individual would pay to access, a company would. What I’d like to do is bulk upload the users and at the same time add them to the relevant subscription level. And for notifications, only have the system send an email that they’ve been invited into the system and to click and create a password (or have it send with one).

I’m checking before I get too far down the line. This is in part because I’ve noticed in a few conversations people can’t have multiple subscriptions – is that true? Mine would probably need to be built that way because people progress through levels of training, but each needs content specific to their course group (i.e. same level training – specific information for the date they took their training) – otherwise I’d end up basically needing to create a subscription for each individual in some instances.

Any thoughts would be helpful! We are running BuddyPress as well so if there is functionality within groups that could let us put the course specific information there – might work! Thanks!
