Hi Simon,
I know of no way other than manually selecting every other Monday in a month
and selecting Nonworking time. Then scrolling to the next month etc.
I was able to record a macro to capture the syntax, but it would still
require editing the macro to each date. I'm not convinced that would be
faster than just making the change manually.
Perhaps one of the VBA gurus will weigh in with a better answer.
