Question

"I'd like to be able to adjust the cost multiplier on a file by file basis. Is there a way, other than changing the cost multiplier for all files of a particular catalog, to adjust the cost to reflect the promo discounts?"

Answer

You can change the cost factor on a design by design basis. See the link below. 

http://www.saberis.com/Support/xpresspos_support_kitchen_options.aspx#Configuring_General_settings

In the XpressPOS Options and Settings Click on the left side Kitchen Button. Then select configure at the bottom.

Under the General Tab, check the “Show Summary form…”

Now when you process a design, the Summary form will pop-up during the process. This gives you a chance to change the cost factor in the Summary form as shown at the #5 red arrow (further down the page). The default cost factor that you set for the catalog in question will appear. Changing the factor only affects the current order and does not change the default.
