Hold Multiple Levels / Visible To Multiple Levels

Events can be made visible to specific membership levels, but you can only choose one.

Members can only have one membership level set.

How then can an event be made visible to two or more membership levels? This goes for other modules as well. Can a person's account have more than one membership level? If not, can levels have parents and children? If not that, can the Visible To filed be set to be able to accept more than just one level? It behaves like that in Studio when setting visibility of various things, but not in the app itself when making a new event or post.

Is there any setting that I'm missing or is this all under "feature request"?
