MQTT: Heihsamon (mqtt client) and Victron Cerbo (Bridge Mode) in parallel

Hello,

I currently have heishamon (mqtt client) connected to the homeassistant mosquitto MQTT broker. Works like a charm as standalone.

Add-on configuration:
active: false
folder: mosquitto

Now I would like to add a Victron Cerbo GX System to HomeAssistant. To do so the Mqtt Broker have to be configured as bridge to mirror the data from the Cerbo GX Device.

To do so, the configuration has to be changed to:
active: true

But then the heishamon mqtt client data is not available any more.
Is it possible to configure the mosquitto broker as a bridge (for Victron Cerbo) and as normal broker (for heishamon) at the same time, to have the heishamon and Victron data available?

Thank you very much,
Armin
