Is it possible to enter a range of values into a field of a lookup file?

I use a lookup file for matching a TCP or UDP port and an application. Is it possible to specify a port range instead of a single port? If so, what is the syntax to do this?
An exemple:

dest_port | application
53 | dns
80 | http
5000-5010| application1

Lookups are exact string matches so putting a range in the lookup file won't work.

By default they are exact matches, but you could use a wildcard lookup like in @Ayn 's answer here http://answers.splunk.com/answers/52580/can-we-use-wild-characters-in-lookup-table.html

So using a csv file like this

dest_port | application
500* | application1

should work for port ranging from 5000-5009

Thank you for your help. Does this apply to ports above 50000 to 50099?

You need to test it; but I assume it does
