Is it possible to direct an expense to a specific service client instead of a job?

SOLVED

I'm new to Sage and the way our system is set up is whenever I enter an expense, I choose an account like Materials and then it forces me to choose a job to associate it with.  However we are trying to split into Constructions Jobs and Service Work and keep them completely separate.  How would I set up those accounts for Service Work expenses since they don't have "jobs" associated with them?  Thank you!
