Switch alert at Tx power on

Which board (stock / gruvin9x / sky9x / Taranis) are you using?
Taranis
What is your openTx FW version?
r2834
What is your openTx EEPROM version?

What steps will reproduce the problem?
1.
2.
3.

What is the expected output? What do you see instead?

In the model configuration screen, it is possible to set an alarm for switches 
position at Tx power on. Very nice feature but would be even better if we can 
select what switch(s) has to be checked. For the time being, it checks all 
switches or none.

For example, I would like to get an alert when I power on my Tx with landing 
gear switch positionned on "retracted" whereas I don't care about other 
switches position.

So, a "tick" box bellow each switch to be checked in model configuration page 
would allow to choose which switch has to be checked at Tx power on.

Thanks,
Didier
