In a wildcard list, you can do things like regex(^http://www[\d].domain.com)
There is also an option to Append to existing list. (export and replace would be even better)
When you append entries that are fomratted with a \, MWG eats the \ and you end up with things like when you wanted [\d].
I figured out that the solution to this is to make my \ entries be \\ entries.
My question -- is this documented anywhere?
