Autofill subject line in Outlook 2011 for MAc

Hi friends, just newbie to this community.

I've been wondering now and then if there's the possibility of setting an "auto fill" in the subject line for Outlook 2011 for Macintosh.

Say, my intention is to always display the name of my business in the subject line, but allowing to further completion. It would look:

[Company Name] — Whatever text is the mail about.

The part in brackets is what I'd like to always appear upon command-new email; without the need to write it every time.

Is that even possible?

Thanks in advance!
