Using Comparators in wM Workflow

I am creating a series of Comparators in a Router to branch based on the contents of a Doc Type field.

Doc Type == AA or BB or CC ------> Branch1

Doc Type == DD or EE or FF ------> Branch2

Can I set up 2 comparators in the example above using an OR condition (If AA or BB or CC then Branch1…If DD or EE or FF then Branch2 )? The alternative would be setting up a comparator to check for each value (If AA then Branch1, If BB then Branch1, If CC then Branch1, If DD then Branch2, If EE then Branch2, If FF then Branch2).

The 6.0.1 WorkFlow Users Guide mentions a “IN LIST” option. I’m not sure if this provides me with this capability.
