For this case I use two identical base folder pairs.
Configure the filter for folder pair 1 to include D:\path1; D:\path2; ...
and configure the filter for folder pair 2 to exclude *\ [which means exclude all folders for this folder pair]

You can achieve this by using two identical base folder pairs:

Folder Pair 1:
include: *
exclude: folder2

folder Pair 2:
include: \folder2\*syncme*
exclude: [empty]
