Category Code flow

Hello,

We are wanting to add some information on a Work Order Category Code and want it to show over on the GL.  I was wondering if there is a Category Code that flows through to the GL or if there is a way to map one to the GL?  Our Accounting department would like to capitalize some of the Repairs so we are wanting to make a drop down list in the Category Code Section of the Work Order to list the types of Work performed by our shop, this way we can create a report on the GL side
