Blank When Zero. Hide Zero in Grid Application?

Hi.
This is an age old question that does not seem to have a solution.

How to hide or not display the zeros in the grid application and especially on the Summary grid?

In the grid application, you can put in the OnRecord event something like this:
if ({Qty}=0) { {Qty} =NULL; };

But what about the Grid Summary?
And also on the Grid Summary Total line?

I have seen some people posting this question since 2013. Hopefully, there is a solution for this now.

Appreciate your help.
Thanks in advance.
