How do I set up “billing codes” (not sure if that is the correct terminology). For some clients we charge a flat fee- EXAMPLE:  Send a letter $50. What I do now is draft the letter, go to the matter, go to time and expenses, go to SUBJECT and type “Draft letter to JOHN DOE”. I then change duration to FIXED and under rate put in $50.

I would like to be able to type in ACTIVITY - LTR and under SUBJECT “Draft letter to ….” comes up and $50 is automatically put in as the amount.  

Is there a way to accomplish this?

Thank you.
