I don't have reaper. Forget Reaper.

Just download Reaper and you will have it.

I just made the script up to do what you need.

When you export the ABC choose an empty track and just export the Chords without notation. And Unfold it first.

Code:
X:1
T:"PopShining" RealTracks with "Held Chords" Guitar
L:1/8
K:F  
Q:1/4=120
R:Shining Pop w/ Held Guitar
M:4/4
