best way to transpose an exercise


I am trying to set up a little exercise to the 12 keys chromatic ascendant. After a certain point I start getting into double flats in the chord symbols and in the key signature. Anyone knows whats the correct way to tell Dorico to keep transposing up a 1/2 step in the easier way to read, so using enharmonic keys.

Thank you for your time

this is the original idea to be transpose by 1/2 step going up

by now I am starting to get Bbb

Sorry to bother everyone, this was already answered.
