Combining Columns in Pivot

Hello. I am looking to identify if there is a way to combine columns within a pivot. In the attached you will see a sheet called "operator Avg Efficiency By Job" It is of course referencing data from the "master data sheet". Within a manufacturing plant we are looking to track operator efficiency by job using the operator clock number. Some jobs only require 1 operator others can require up to 4. Problem is the same operator depending on the day and the job can be in any spot within columns T-W on the master data sheet depending on how many people run the cell. I would like to figure out a way that it can grab all of the operators no matter what column they are typed into and get it to consolidate into one column in the pivot with the OEE related back to the job they were working. Let me know if this makes sense....i could probably clarify this more.
