Here is a way you can see an overview of your whole system. This can also be used to track subsystems. By using features of databases, you can have all of your members in one database, but listed by subsystem. Below, I’ve created an alter who is tagged under “Subsystem A”. All members are listed above, but by using a filtered view below, I can only see members of the subsystem. Filters can be accessed using the three-dots menu when hovering over the members, and is very expandable.
