Can I use 1 ET340 or Em540 to measure the output of 2 grid inverters rather than 2x ET112

Hi,

I have an Aurora PVI3.0 and a Fronius Primo 6.0 that will function in parallel. I understand the Fronius can be monitored and controlled via Ethernet (if I remember correctly) but I don’t believe there is any way to monitor or control the Aurora. Rather than buy 2x ET112 and monitor individually and use an extra port in the Cerbo, is it possible to measure the output of both inverters individually through 2 of the 'poles'with either a ET340 or EM540 and then the 3rd pole use for output to the grid/export? I'm hoping the 2 PV solar poles coukd be combined to give 1 solar generation amount into 1 reading in VRM? And the 3rd pole would show 'to Grid' in VRM.
