Assigning phase to single-phase virtual PV inverter?

I have a SolarEdge inverter that is detected directly by my Cerbo. This is a single-phase inverter connected to L2, and in the device settings I can assign it to L2 without any problem.

In addition, I have two other single-phase inverters, one on L1 and one on L3. I created these as virtual devices and I am feeding them data manually. That part works perfectly.

However, as far as I can tell, a single-phase virtual PV inverter cannot be assigned to a specific phase. Is that correct?

At the moment, I have created them as virtual three-phase inverters and I only provide data on the phase they are actually connected to in real life.

Is that the correct way to do this, or am I overlooking something obvious?

I would be very happy to hear your thoughts. Thanks in advance!
