Does anyone know whether it is possible to copy the Multiriffs and bar settings from one project to another?

I'm trying to save an old project I made that had multi-drums in the style, which is still causing problems after I tried to substitute the drums with drums that has stems. The stems show in the mixer but won't play. Actually, the audio waveforms from the stems are non existant when I click on the tracks tab.

Some time ago, Simon mentioned the way to avoid this problem is by not using styles with multidrums.
So with all new projects I've been choosing styles without multidrums.

I was hoping I could save an old project by copying the chord sheet, with all it's settings, so I didn't have to do all the legwork with assigning multiriffs, etc.
But, I noticed after I'd copied everything over to the new project, the multiriffs and bar settings didn't copy with everything else.

Is there a way around this?
If not, is there a way to identify which multiriffs are being used?

I apologise if this has already been answered elsewhere.

Thank You.
