[Xymon] backticks not working in client-local.cfg

Xymon version: - Xymon 4.3.10 OS: - Ubuntu 12.04 LTS

**I am using the below entry but it is not converting the date command to the value.

[server-name] log:/mnt/logs/access.date +%Y-%m-%d.log:10240 ignore INFO trigger SEVERE

I tried many things but no luck, on the log page I see the date command as it is instead of the actual date value.: -

log:/mnt/logs/access.date +%Y-%m-%d.log:10240 log:$(/mnt/logs/access.date +%Y-%m-%d.log):10240 log:$(echo /mnt/logs/access.date +%Y-%m-%d.log):10240 log:/mnt/logs/access.$(date +%Y-%m-%d).log:10240
