dynamic comment

Hi,

is it possible to use a dynamic comment in bb-hosts? In Big Brother I patched mkbb2.sh to display a phone number next to the name that changed depending of the time of day. These phone numbers were taken from a separate config file. But with  XYmon I only can put a comment to the line in bb-hosts and it is no solution to run a script that changes bb-hosts every time a number has to be changed. I'd like to have something like "COMMENT:$SCRIPTNAME" and this script then is called and gives you back the phone number that is then displayed next to the server name as comment.

TIA Torsten
