Auto bind volumes on core update of homeassistant container

Configuration
1

Hello folks.

I run homeassistant in supervised mode. I have integrated my external USB hard disk into homeassistant. For this I make a bind to the host. So that I can see the hard disk capacity via configuartion.yaml.

- type: disk_use_percent
  arg: /mnt/extHDa
- type: disk_use
  arg: /mnt/extHDa
- type: disk_free
  arg: /mnt/extHDa

This works great. Now I have the problem that the homeassistant container is rewritten with every core update and I have to manually create the binds again. Is it possible to automate this somehow?

Cheers Gabriel
