Quick way to convert faces to DXF's?

I have multiple bodies I plan to cut from 1/4" Plate and need to convert it to a DXF for our burn table to use. I find it monotonous to hit save as, use the drop down menu, then name that part. I was hoping someone had a quicker way to click a face (or multiple) and convert it to a DXF format.

I have already done it for this project, but I am sure it will come up again.
