Add preference to write messages to the log

[RuebeDo]

Hello,

i am looking for a preference to write messages to the log for better visibility of different jobs when every job writes to the same log. For example, i write all messages from different jobs (profiles) to logs named on a daily base. It would be nice, when I am able to sent out from the profile messages to job when he is activated. Suggest here something like messagetolog = start Job XYZ starts messagetolog = end Job XYZ ends
