Monitor multiple syslog files with one entry in clientlocal

We've set up our network devices to syslog to the xymon server.

So in /var/log/xymon-syslog there are several syslog files, one for each device, and the files are named net-hostname

In client-local.cfg, can I set up one log entry to read all of these files?

Meaning, should the following be valid:

log:/var/log/xymon-syslog/net-*:10240

Its not working, as xymon reports no such file or directory, so the regex isn't expanding to find all filenames. So I'm wondering if anyone else is doing something similar?
