Thanks to everyone for all the great suggestions. I had forgotten about these work-arounds. Turns out that Peter’s suggested Style # 1547 is what I needed for the desired bass line, with some editing. Thank you, Peter.

When I initially assigned the RT bass track, my first ‘filter by’ was too narrow and subsequently, became too broad, resulting in too many results.

To bring up Peter’s recommended Style #1547, if I had entered ‘ country swing bass’ in the ‘filter by’ slot, only 4 options would have been displayed.

Hope this makes sense.
