Classical chords notation +4 +6

HelloDepending on the music I write, I sometimes use classical harmony chord notations in my scores like for example:

. F+4 instead of G/F,
. F+6 instead of Bb7/F
.G b6 instead of Aø/G
2
.F 6 instead of Db7/F
5 (crossed out 5)

But when I propose these notations, Dorico interprets them differently and changes them for other chords that are not the same. Is there a way to use your own notations ?
Thanks for your answer
