New Calculated Grid Column

Dear all, Is there any possibility in a grid to add a "new calculated" (arithmetic operators and/or basic formulas) value from available table fields (without any customization I mean).

I worked on another ERP which let us the possibility to do that (java/html platform) ?
All I can see in the documentation is to select/unselect amoung available fields in the form.

For instance, I wish to add a new column giving the delay (two dates and/or two hours fields) or quanty (i.e/ Shipped quantity - ordered quantity * 100) or amount (margin = amount - cost) or percentage...

Thanks
