Yes you could. In this case, you would have to add Custom Capabilities. This is an additional “category” that you will decide (you can call them however you want). You can call one ccap “alpha” and one “beta”. So it would go this way:
Member 1 has Level 2, ccap “alpha”; they will see content that is limited to “alpha” in Level 2,Level 1 and Level 0
Member 2 has Level 0, ccap “beta”; they will see content that is limited to “beta” in Level 0 only
Member 3 has Level 1, ccap “beta”; they will see content that is limited to “beta” in Level 1 and Level 0
If, at any point, you need to have one member have access to “alpha” and “beta”, then you can give those members both access.
Watch the video on Custom Capabilities, at the bottom of this page. The ccaps are SOOOOO powerful. I use them on just about everything in my site, whether it is for a course access, workshop, forum, etc.
