How to Add Single Note to Pattern 1

How to Add Single Note to Section C, Pattern 1?
Need slot (1) to be a note not a chord.
Single Note–>Chord–>Chord–>Chord–>Single Note–>etc.
Section A identified the pattern correctly, but doesn’t allow single note to be drag/dropped to Section C.

Which version are you using? I know this was corrected in the latest. But the easiest way is to go to Edit Chord and just click on the note you want there, simple. So if you want an A2 click on a blank pattern spot, choose Edit Chord, Click on A2 (remove any notes you DON"T want) then you are done.
