Logical switches Teacher Student Variants

Hi,
done this
www.jetimodel.com/en/DC-16-amp-DS-16-1/L...Teacher-and-Student/
but would like to able to go to Teacher mode by moving a stick
OR hit the momentary switch again
From
3. If the Teacher wants to take over the model control again, the Teacher simply moves the ailerons or elevator stick.
would like to have a first variant:
3. If the Teacher wants to take over the model control again, the Teacher simply moves the ailerons or elevator stick
OR push the momentary switch

or preferably a second variant, with a 2 position switch (not momentary), for example Sh,
the Stundent switch, on/off and something like spektrum master override feature
2. The Teacher moves the control sticks to the middle position and put the Stundent switch in on position.
This passes the control to the Student transmitter.
3. If the Teacher wants to take over the model control again
- the Teacher simply moves the ailerons or elevator stick (3.a)
OR
- put the Stundent switch in the OFF position (3.b)
4. The control is given back to the Student by sticks to the middle position
AND
case 3.a : reset the student switch (put the Stundent switch in off position, than in on position)
case 3.b : put the Stundent switch in on position

Thanks
