Macro for link in emails

[jimj]

Hello,
I'm wondering if there's a way to add a link to email alerts that would provide the URL to the problem? I looked around on the macros page and could find any that might provide this. I'm hoping to have my email alerts look something like:
***** Nagios *****
Notification Type: PROBLEM
http://<nagioshost>/nagios/cgi-bin/extinfo.cgi?type=2&host=somehost&service=Partition+%2Fbackup
Service: Partition /backup
Host: somehost
State: CRITICAL
Alert Details:
DISK CRITICAL - free space: /backup 89638 MB (6% inode=98%):
