Boat page modifications

Hi,

I would like to change the Boat Page to add control of a Marine AC Unit connected to Cerbo via CAN bus (adding a small GUI).
How would you proceed in this?
As both CAN Ports are used (one for NMEA and one for BMS) I would need to add a USB to CAN interface. What would be the one recommended to use?
Many Thanks for your thoughts,
C.

I’m using Cerbo GX in version VE.CAN and BMS.CAN
The new GUI is used in the latest Version v3.70~23
