Multiseat -Display numbers from the xservers are vary after each start

I am running a multi seat system with several graphics cards.
At the moment I am using lightdm as desktop manager.
I realized, that after each system start the display numbers vary.

Vary means:
   Restart                              123456789
   Seat0   Desktop number   011010001
   Seat-1  Desktop number   100101110

Even if I mapped the GPU to a specific seat and desktop number.

I would like to know if there is a way to setup a deterministic multi seat system where  every time atfter a restart the desktop numbers are as specified in the config files.

Does anyone has an idea about this?

An abstract from the current config files:

xorg.conf
   ...
   Section "ServerLayout"
       ...
        Option          "Seat"  "seat0"
    ...
   EndSection
   Section "Device"
    ...
        MatchSeat       "seat-1"
    ...
   EndSection

lightdm.conf
   ...
   [Seat:seat0]
   xserver-command=/usr/lib/xorg/Xorg :0 -config xorg_seat0.conf -sharevts -keeptty
   [Seat:seat-1]
   xserver-command=/usr/lib/xorg/Xorg :1 -config xorg_seat-1.conf -sharevts -keeptty
