I am trying to set up a workbook with multiple tabs and two signature lines at the bottom. The idea is that my boss can read, sign and close my work as necessary.

The problem is that each time you sign a tab/sheet, it converts the whole workbook to read-only.
I only want one tab/sheet as read only.
It will just be too much to have 100 separate workbooks for us to keep track of for this function.

I need any ideas I can explore. Thanks.
