I can't set the tempo wherever I want to.

I want to make a tempo change within Synth V that’s smaller than a quarter note, but as it turns out, it only snaps to the closest quarter note, and not where I clicked. If a MIDI file that I’d created (such as using Guitar Pro or Musescore and exporting that MIDI file) where the tempo has changed in a place smaller than a quarter note, then it’s allowed. I want to do that, too, within Synth V itself.
