Single Courses with members areas?

Can you sell single courses with squarespace members areas? Or is there another way to do this? For example if I had one video that was roughly 2 hours long, could I sell this as a single course? 

I'm wondering something similar. I was hoping to set up a site where customers can pay for individual online workshops, but Squarespace doesn't seem to offer this. It's either a fixed fee for all video content you upload or a subscription to it. Unless you set up multiple Member Areas.

I find it really complicated and a bit long-winded if I'm honest, and I'm concerned customers will turn away if there's too many barriers for them accessing my work!

I'm needing help with this too. Right now I have 2 courses, each have their own member area. To: Ash97, you can only have up to 10 courses on your site which means 10 member areas. 

My struggle is that I want people to be able to have the option to buy both courses. Like add both to a cart and checkout at the same time. But having to join 2 different member areas makes no sense.
