Is your feature request related to a problem?

When doing training with new pilots I set a logical switch that gives the control back to the master when a stick on the master radio is slightly moved (referring to source stick). I think that's a very common method and it works fine as long as I use the slave signals in mixers.

But I cannot use the Special Function "Trainer" with this method. It seems that the function simply replaces the values of the master Sticks with the values of the TR.. signals. So when the student moves his sticks the control is immediately back at the master radio. If the master has his sticks in neutral position the control then goes back to the student again. And so I end up in an endless loop.

Describe the solution you'd like

Proposal: Can we have four additional sources to use with the logical switches. These sources should always represent the sticks of the master radio (and never be swapped to the TR.. values of the slave radio).

Describe alternatives you've considered

As a workaround I use a mixer for every stick to switch between trainer and student (two lines for every stick). Then I change the source of the Inputs to these channels (instead of source Stick). This works very fine for me, but it is time consuming and hard for the average (or new) user. We have ten Opentx/EdgeTx users in our club and it seems that I am the only one who can manage that effortless.

Additional context

At the moment I still use OpenTX but I guess it is still the same with EdgeTx. If not I apologize for bothering you.
