Condition to toggle light depending on the state of another light

Configuration
1

I have separate light switches for the hallway on each level of my house (basement, ground floor and second floor), Separate to this I have light switches at the staircases to control the light on the upstairs and downstairs. All light switches are planned to be extended with a shelly device to be able to control them also via home assistant.

Now it sometimes happens that the hallway light on the second floor has been turned on. You have enough light to walk downstairs and arriving at ground level you recognize you cannot turn off the light. So I would like to add this opportunity. The idea is to long-click the stairways light switch to toggle the hallway light on the second floor.

Towards the basement I would like to allways turn on the basement corridor light light.corridor_basement, when the light switch for the downstairs lighting is pressed. But the basement corridor light should remain to be controlled separatley from the downstairs lighting.

#        - light.corridor_basement #TBD Ensure that it toggles to the same state!

i.e. the light.corridor_basement only needs to be toggled, if it is in the same state than the light.staircase_down. Is there anyway to add this condition priort to calling the toggle of light.corridor_basement ?
