How to affect the order in the list of sessions ?

[teto]

Describe the bug

my tuigreet lists ~5 sessions, 4 gnome sessions (including redundant ones I think ?), and one for sway, my main session.
When restarting my machine, the default select cmd reverts to "gnome" (I am on nixos). Desktop files seem to be sorted alphabetically ?
I wonder if I can influence the list in one way or another ?
e.g., I would like "sway" to get selected by default .maybe "--remember-user-session" should do that.

sway appears first in --sessions

              "--debug /tmp/tuigreet.log"
              "--remember"  # remember last logged-in username
              "--remember-user-session"
              "--user-menu"
              "--time"
              "--greeting 'Hello noob'"
              # TODO make sway the default wrapper
              "--sessions ${config.home-manager.users.teto.home.path}/share/wayland-sessions:${sessionData}/share/wayland-sessions"
              "--xsessions ${config.home-manager.users.teto.home.path}/share/xsessions:${sessionData}/share/xsessions"
              "--power-shutdown /run/current-system/systemd/bin/systemctl poweroff"
              "--power-reboot /run/current-system/systemd/bin/systemctl reboot"

with

 tuigreet --version
tuigreet 0.9.1 (x86_64-unknown-linux-gnu)

Additional context
Unrelated comments:

• "--remember" would be more self-explaining as --remember-username ?
  I would appreciate a more detailed example for "--session-wrapper ". I tried to create my own but it failed. I had nvidia driver issue at the time so maybe that's why it couldn't launch. Maybe I need to retyr.
