Control panel for two Battery systems 12V and 48V

Hello,
For an offgrid boat installation I am planning to add a 48V LiFePo4 battery system to an existing LiFePo4 12V system. I am currently using a BMV 702 in combination to a Victron Energy Color Control GX to monitor the 12 V battery.

Is it possibile to monitor both battery with the Color Control? or do I need a second one or is there a monitor from Victron that can handle two batteries? do I need a second BMV?

Thanks in advance for the help!

yes the BMV702 can monitor 2 batterys but only the Voltage is monitored on the second battery, and you can see both on the vrm if you have set this up

first of all thank you for the fast answer!
So the BMV can monitor both batteries but the color control can only display one, is that right?

Also very interested in this as building a similar system and trying to figure out if I'll need two networks or if they can all be on one. E.g. 1 colour control or cerbo gx can monitor both batteries. I'll be using REC BMS.
