Network/Multisite

I have been using Podlove for a while for a single podcast but I am going to make a separate site with many podcasts. I tried “Shows” but I felt it wasn’t powerful enough. Now I am trying multisite and I am having some problems.

The big problem might be the lists since I simply can’t create those. I go through the options but no list shows up and no error reported. It is also weird that I can select or upload any image when creating a list.

If I am understand lists, though it isn’t easy to search for the topic, then they are the key to connect podcasts from the sub-sites together. But, if I am wrong, what tools do you use to crosspost and connect different podcasts?
