Blind end of day - feature request

A previous till I used to use (epos now) had a function to set a user account for blind end of day. 

This meant that the staff member could perform the end of day procedure but not able to see the total takings for the day. 

This is private information that I don't want my staff discussing. I was horrified when I found out one of my main staff who sometimes performs the end of day was telling friends and family updates on how much the shop has been taking each week. He was going on and checking the end of day screen throughout the day and updating all the staff on shift. Obviously we dealt with it our way with them.

Now we have a secret account on the till that is only used by me and my husband but it means we are the only ones who can run end of day to keep this information private. 

We are both going on holiday and we are going to have to give them access again to the takings totals. Which I am not happy about. it's either that or don't run end of day for a whole 14 days. 

If you can introduce blind end of day, for it to be able to be run without being able to see  how much money was taken, this would be ideal for us. I suppose it would be helpful for other business owners too.

Many thanks,
