Ok, as it greatly annoys me when people respond to my "request" post as if they were a "how to?" post, then after reading your other (more detailed) thread about this, I decided to rather put the following into this one:

While waiting for a proper implementation, you can go the long route and re-type the desired chord 4x over into each bar, turn the "Ignore slash" checkbox ON in song settings, and use a Held bass (either one of the existing ones or check the "Held" checkbox in the main RT Picker interface).* This will give you a factory RT bass which repeats the same note on each quarter beat during a single bar, just as you wanted...well, 99% of the time, just to cover myself here.

I know it's not the quick'n-easy thing you prefered (and that's obviously where your Request post comes into this), but it's the closest to next-best I could think of.

*It might be an idea to do this after you've rendered all the other tracks to your liking and freeze all but the bass.

Just because you can, doesn't mean you should!
