Hi Gary, Welcome back, also

If I follow what you are looking to achieve in some way, I really believe this is the easiest way, so try this:

Start the song using the style: _BOSSANQ

Then at bar 8, press the function key <F5> and change the style to _J140_BD, optionally placing a Part Marker on bar 9 to introduce a drum fill

At bar 16 press function key <F5> and revert to _BOSSANQ.

Rinse and repeat every 8 bars with optional Part Markers on the following bars, and the song will go from Bossa to Swing.

This should get you going in some form at least. Good luck (with everything).

The layout should (might) look a bit like this:
