Spark Stripe Quantity Plans

Hello! My application has two different types of users, one for employers and one for job seekers. For now, the employer is the only type of user that I would like to charge and this will be on a per job, per month basis. So the incrementQuantity/decrementQuantity functions look perfect for what I'm trying to do.

My question is, is there any support for this in Spark? I haven't seen anyone talk about this.

Thanks for your help!
