Watch Topic Scan Question

[TBlack]

When setting up Watch Topic Scan, sometimes it makes sense to scan two or more Topics, i.e. Sorted and UnSorted. It seems NB can only scan one topic at a time. I can type in two topics to override the dropdown using a "|" between them, but the scan does not proceed. We can set up alternates using "|" for subjects and posters, how about Topics?

Thanks
