Hello
In the subject of secondary groups, SOFiMSHC does not have the same functionalities as SOFiMSHA. SOFiMSHC only uses the logical operator AND. So it’s possible to use multiple BBOX commands, but it doesn’t have the effect you expect.
If you want to have full controll over the combination operation, you have to use SOFiMSHA.
This is quite simple, just add an additional SOFiMSHA run after the SOFiMSHC modul with the coman SYST REST (see your linked post).
