solver configuration for many physical networks in Electrical Simscape?

Dear experts,

I have a Simscape electrical model (using "power system" technology) with many physical networks. Is there any way to put only 1 solver confirguration block just like in "specialized power system"? If not, is there any way to calculate the number of physical networks in the system and how to know where should I connect to solver confirguration blocks?

Thank you in advance.
