Transposing instrument workflow

I am transcribing an orchestral score and can't figure out how to get the correct workflow for transposing instruments.

When I enter notes on my digital piano, those are concert pitches. The piano is not a transposing instrument. And I want MuseScore to then write the correct written note for that sounding pitch. I don't want "Concert Pitch" on, because the score I'm transcribing isn't in concert pitch. I want always to be able to visually compare the two scores, and immediately know if I've made a mistake.

I can see how the "concert pitch" workflow can be very useful -and even that it is designed to make this easier- but what I want is total non-interference from Musescore. Its extra assistance is driving me crazy.

1. I read the note in the score correctly. Meaning (as the arranger and not the player) I transpose it in my mind so that the note I read, say, and play is the concert pitch.
2. I play that pitch
3. Musescore instead writes notes as if I'm blindly copying without understanding what I'm reading.

Please tell me there is a way to do this the right way. Whatever the conventional way is in contemporary software, the default behaviors are not how transcription works. If -as a working musician- I sit down with an orchestral score and play it, I am not playing transcribing instruments "as written" or I lose my job. Likewise if someone plays notes for me on the piano and asks me to write them for -say- alto sax, I transpose the sounding notes -which are playing out loud and therefore concert pitch- to the correct written notes for that instrument, or -again- I lose my job.

I very much want MuseScore to work this way. Have I missed a setting somewhere?
