Merge Data from specific columns of multiple workbooks/sheets into an Existing Master file

Hi,
I have an existing Master workbook which is being used by numerous people to obtain updates. The updater filters by their territory, makes their updates and then save the workbook with a different name (adding their initials to the file name). The new workbook is then returned to me for updating on the Master workbook. There are currently 35k+ rows and columns A-W. I don't want to copy and paste all the updates into the original workbook. The columns that need to be updated are V-W. I am looking for a formula or macro that can be run to copy the information in these 2 columns on the individual workbooks/worksheets to the master workbook/worksheet. I have looked at several posts on this site, but I didn't see any that worked for this application. Any help you can give is much appreciated.
