Advanced text filtering in Alert profile

To monitor link errors in Eventlog analyzer, we currently have configured an alert profile which is triggered on text (log message contains):
"%LINK-3-UPDOWN: Interface Serial"

The problem is that both Link up and link down messages hit this Alert. We would like to specify a Link up mesage in another profile then an link down message.
Also, the Serial interface is specified in the syslog message (eg. Serial0/0 or Serial 0/1 or Serial 1/3 etc), which makes every syslog message Unique.

To solve this issue, We would like to have the option to use AND/OR statements in the alert profile (just like the Firewall log analyzer does).

Do you have any solution for this issue?

Thanks in advance.
