Dang - I almost wish the answer had been a LITTLE harder than that.
Don't know why I didn't check that button again, after I got more into doing stuff.

Lots to explore under the Advanced Button of those presets.
Have you gotten into selective export of Timeline content yet? If you do, that is a 2 part must do
1. set the gray tabs of the Work Area Bar to span the segment for selective export
2. in that export area, have a check mark next to the "Share Work Area Bar Only" option.
Please do not hesitate to ask questions or to ask for clarification. Every question is important if you do not have
an answer for it.
