Trying to add total row to stock balance report

Hello all,

I am attempting to add the “add total” row to the stock balance report, which is something my employees will need to access regularly. When i click on stock balance → click on menu → click on edit → check “add total row” I get the message
"Only administrator can create standard reports, please rename and save.

Any help would be greatly appreciated,
Lee
