Bridging IS0 Tx Neutral and Auto TX Neutral in a Marine Application

I have a boat with a 50 Amp shore power feed going into an ISO TX. The Neutral and GND are connected on the output of the ISO TX. From there the ISO TX output goes to a Quattro 8K 230v Inverter (Hot 1 and Hot 2) and the Shore Power selection breaker (Hot 1, Hot 2 and ISO TX Neutral).

The Inverter feeds an Auto TX which is then connected to the Inverter selection breaker (Hot 1, Hot 2 and Auto TX Neutral).

The ISO Breaker and Inverter Breaker have a lock out only allowing one to be selected.

My question is: When AC power is going into the Inverter (not inverting) and being passed to the Auto TX and the Inverter breaker is selected should the ISO TX and Auto TX neutrals be connected?

When the Inverter turns on the ISO TX and Auto TX neutral disconnect and the Auto TX would create the Neutral/GND connection.

Please see the attached wiring diagram.
