4 Bar Analyses Instead of 8

The intro of a song I’m analyzing is only played for four bars (16 beats) but Hookpad requires that you have at least eight bars (32 beats) for a proper analyses with a Youtube video. Is there any way I can just have 4 bars?

You can drag black bar at the end of the line to change the number of measures to whatever number fits the song you are analyzing.
