I'm using Mac OS X, and I'm struggling to get mpremote to do anything more than giving me a REPL.

This is the list of devices I get when trying to connect to an ESP32 DevKitC1 board:

mpremote connect list

/dev/cu.BLTH None 0000:0000 None None
/dev/cu.Bluetooth-Incoming-Port None 0000:0000 None None
/dev/cu.usbserial-0001 0001 10c4:ea60 Silicon Labs CP2102 USB to UART Bridge Controller

Issuing mpremote connect /dev/cu.usbserial-0001 connects to the board and gives me a REPL back. But any other command (fs, run, exec...) won't work as mpremote always assume that the device is has to connect to is the first in the previous list (/dev/cu.BLTH in my case).

As mpremote CLI syntax does not seem to allow specifying both the serial port to use and the action to perform (imagine something like mpremote -D /dev/cu.usbserial-001 fs ls), would it be possible to consider a shell env var à la ampy (or minicom) to tell it what serial port to use?
