Users are downloading a spreadsheet where they should be filling in important
values to HR such as Name, Last Name, Social Security, etc.
Besides there are other values such as Standard number of hours they work
(20, 37.5, 40, etc) that are being used to calculate overtime, benefits, etc.
so they must be filled in.

Is there a way to make these fields required before printing/saving the
spreadsheet?
Thank you!
