Remote Upload and Monitor not using environment config

I want 2 different environments, for local and remote.

I have this in my platformio.ini :

[env:remote]
upload_port = /dev/ttyUSB1
monitor_port = /dev/ttyUSB1

[env:local]
upload_port = COM4
monitor_port = COM4

By using the remote monitor (or upload, but it behaves the same), the port used will be the first specified (in this case, /dev/ttyUSB1).

It seems that upload_port and monitor_port aren't taken into account properly when using remote actions. It works when using monitor on the current machine however : the right port is used.

Can you please fix the remote actions so that it uses the ports I specify in the environments ?
