To add to Del's suggestion, most of the time I set the resolution higher, 1960 or 3840.
Instead of the beats being defined in 1/120th sections they are much smaller at 1/3840th.

That way you get finer 'chunks' when editing.

It is under Options - Resolution.
Also much like Del's example I often use the little arrows in the Edit window.
Single arrow goes to the start/end of the measure, so you would only have to input the desired measure numbers correctly, then the arrows fill in the rest.

The double arrows go to beginning/end of track.
Just another little time saver following along the same idea, different workflow.

So if you quickly highlight a section and it ends up being 32-1-3 thru 34-3-38 you can use these little arrows to quickly define the whole measures, assuming that is the goal.

Make your sound your own!
