Is it possible to use Regex in a Group or AppliesTo filter?

Hi,

I need to filter a specific number of machines into a group or datasource.  The filter is any machine that has the letter ‘c’ as the second-to-last character before the first period in a name.  E.g.  abc1.company.com.

I have some Regex that will do this ( [^.]*c[^.]\.[^.]*\.[^.] ), but when I try to use it in an AppliesTo it just fails.

According to this page: https://www.logicmonitor.com/support/terminology-syntax/scripting-support/what-is-lms  I should be able to use =~ or !~ but they both give errors like this:

I tried putting it in quotes, parenthesis, quotes and parenthesis, and I couldn’t get it to work.  I opened a ticket and they are going to look into it, but I thought I’d post here in case anyone knew if this is possible or not and how to make it work.

Thanks!
