Can I specify a regex in a lookup table to group similar requests into the same output lookup?

Hi,

We would like to create a look up table based on some user agents.

Mozilla/5.0 (compatible; Traverse/0.1; ABC 22175) Mozilla/5.0 (compatible; Traverse/0.1; ABC 23457) Mozilla/5.0 (compatible; Capture/0.4; ABC 56439) Mozilla/5.0 (compatible; Capture/0.2; ABC 98123)

I would like to group similar kind of requests in the look up table and save them into Field XXX.

So field XXX should show Traverse 2 requests Catpure 2 requests

So can i specify reg ex in the look up table as there will be multiple patterns which i would like to group them.
