I am not sure I fully get your question, Jürgen.
The "Anchor" Circle is a Circle defined by the Holacracy Constitution: It is the "first", the "highest" Circle.
A "General" Circle is not defined by the Holacracy Constitution. However, many Holacracy-powered companies have a "General Company Circle" (GCC) as a Subcircle to the Anchor Circle. (HolacracyOne does this, see here. At Structure & Process, we used to do this, but got rid of it, see here.)
If you find that your Anchor Circle is crowded up with too many roles, creating a "Company" (or "Operations", or "GCC", whatever works in your context)-Subcircle might be a good first step.
Does this help?
