Disable automatic note regrouping

Is there a way to disable the automatic note grouping completely?

It annoys me when the notes length is changed into something similar when I enter them or when I add a tie.

I am aware that there is the option to change this, but none of the option satisfies me. Depending on the rythm the grouping might has to change from one bar to the next bar.

If this is somewhere documented in the online help, then I did not find it. Sorry.

Lock Duration (“O”) is what you seem to be looking for. But used all the time, it makes Dorico less efficient at doing what it is designed to do.
