How to influence automatic Battery Monitor selection

Hello,
in settings/system setup/batterymonitor you can either select a specific monitor or use autoselection.
Is there a possibility to influence the automatic selection sequence, means can I specify a primary monitor, secondary etc... by naming monitors accordingly?
I found a ticket https://github.com/victronenergy/venus/issues/901 with a similar topic explaining that the monitor is selected based on alphabetical order.. But I assume this includes the source path like CAN, serial (USB) etc as well - is there a more detailed explaination somewhere?
E..g. I have several serial monitors, use the Battery Aggregator and have a Lynx Shunt (ve.can) connected. I would like to ensure that first the BattAggreator is used first then the Lynx Shunt.

I can't remember where but I read somewhere a Victron document that the other of priority is BMS first and then shunt. Nothing to do with the alphabet.

hmm the serial BMS typically reflects one single pack only but BatteryA. & Shunt are overarching so would make sense to use them first.
Alphabet is mentioned in the ticket linked- but alphabetical order most likely includes the device path which should group dbus, can.... first.
