Have you tried slash chords. If you input the following on the four beats of a measure you will get a walking bass, CMaj7/C, CMaj7/B, CMaj7/A, and CMaj7/G you will get four beats of Cmaj7 with the bass walking C,B,A, and then G. Of course you do not need to add four chords as you can have a C/C for 4 beats followed by a Dm7/D for 4 beats and get the tonic note in the bass.

Good luck and I hope this helps.
