Precise minute and second measures

I would like to be able to work in seconds to exact timecodes and have the cursor stop and start at the exact times regardless of measures. For instance, write a piece of music from
0:00:10:12 to 0:00:22:13 Dorico doesn’t want to do this at the moment. I have to be able to work to timecodes, will this be possible in Dorico?

When you say “cursor”, do you mean the caret for note input, or the playhead during playback?

It’s true that Dorico is not entirely suited to writing music based on fixed time rather than on bars and beats, but depending on what kind of notation you’re looking for you should be able to get pretty close.
