Amending Formula in Financial Reporter

I don't know if this is possible - I have a budget report and on most of my lines I have \ that picks up all the values related to the line.  For particular reporting this year, I have to deduct a value from that amount - I can't specifically adjust the coding to exclude an account number because I need part of it to show up.

For example, I need all the numbers less an arbitrary $8800

Otherwise, I suppose I can figure out what the line is supposed to be, subtract off the $8800 and put the actual value in, rather than figuring out the formula.
