Upload to multiple IP ports to identical devices

I wonder if we could upload to multiple ports at the same time with PlatformIO.
I have four test processors on the same network. I use their DNS names to upload them one by one. I wonder if I could to something like this

upload_protocol = espota
upload_port     = test1.local, test2.local, test3.local, test4.local

The Doc says “upload_port Type: String (Pattern) | Multiple: No”.

See upload_port — PlatformIO latest documentation

Yeah but is it possible somehow?

Running multiple CLI commands in in parallel terminals: pio run -t nobuild -t upload --upload-port <ipaddress>

Thank you very much. Will give it a try!
