Request for the posibility to use BTRFS as option on the OMV.ISO install

I understand that Ext4 is used by default if you use OMV.Iso to install on bare metal, and that is possible to install debian netinstall image first and use BTRFS for boot disk and later install OMV on it,

But my request is, if is possible to select BTRFS or Ext4 en the OMV.ISO install step so users can decide in that step of the install process.

With a BTRFS install of OMV on Boot Disk, doing snapshot or use Timeshift are really easy and quick, so i think that is a good must have for the boot drive.
