Attachments ATC1 Table - Need to add UDFs to the attachements in Sales orders

We need to create a Sales Order Form that prints Before and After Pictures.

I have it all packed down except that I need to print pictures of the job performed Before and After.

If there a way to add a UDF to the ATC1 table or some other way where I could tell from each type of attachement what category it belongs to.

I need to know wich attachment is BEFORE the work was performed and which where AFTER the job was performed.

HELP....
