Is there a way to get Arduino IDE to pass --host_port (-p) to espota.py?

[sprior]

I recently set up a VLAN for my IOT devices so they live in a more secure network with a pfSense firewall between my development laptop and the devices. I am trying to restrict what port connections are allowed between the two networks.
I have set up a MDNS bridge between the networks so in the Arduino IDE I can see the esp8266 devices as available network ports.

What I have discovered is that the espota.py tool requires the esp8266 device to connect back to it on a host port and by default that port is random between 10000 and 60000. This works great when everything is on the same network, but in a firewall situation would require quite a large port range to be opened. espota.py does take a --host_port (-p) option to specify the port which seems promising, but I haven't found any way to configure the Arduino IDE to invoke espota.py with that option specified.

As a temporary hack in the
group.add_option("-P", "--host_port",
section I replaced the default = random.randint(10000, 60000) with a default =
but I dislike this option because it'll go away when I update.

Is there anywhere less fragile where I could set this as a preference?
