In Reaper I insert markers for the start of the intros, verses, chorus etc. As long as you set the tempo map in your DAW your golden. I do a lot of track editing in the DAW instead of using Realbands multiriff function. I sometimes find it useful to drop markers at the chord changes and rename the marker with the chord name. This does take some time up front but can save a lot time later on. You could layout an entire chord chart in markers if you wanted to. It does tend to get pretty cluttered in the track pane though.
