Linking Multiple Workbooks To One Master Workbook

At our small firm, each staff member keeps a small excel spread sheet on the network that contains their "work in progress." This spreadsheet is roughly six columns wide and roughly twenty lines long.

What I am attempting to do is have one "master" spreadsheet with a tab for each staff member that links their "work in progress" so that partners and managers can easily see how much work each of the fifteen or so staff members have.

I can create fifteen different tabs and fifteen different files on the network and link =[Staff1.xlsx]Sheet1!$A$1:$G$25 =[Staff2.xlsx]Sheet1!$A$1:$G$25 =[Staff3.xlsx]Sheet1!$A$1:$G$25 and so on.

If I make a change to the layout of the work in progress sheet, I have to delete and copy the file fifteen times, then go back through and re-link fifteen tabs to fifteen workbooks in order to keep it uniform.
