Better identify in the template about which columns are mandatory

[jstewart-ebi]

There is not information in the template about which columns are mandatory, you only know once you upload the file. MC
The orange-ish highlighted columns are the mandatory ones. Check that this is clear in the documentation. Maybe we should also add it as a comment in the spreadsheet itself? - ES (Sorry, I did not read the documentation, some users will not do either unless they cannot upload?-MC)
Suggest add “(Mandatory)”/”(Optional)” to each column description

I feel adding "this column is mandatory" to each mandatory column would just inflate the column description. But doable of course.

I'm adding a VBA script to the excel file so a pop-up will show up on opening the template. Although we have to check with Tudor to make sure it won't screw up the backend.
