Quantity by step

[delighted]

Hi everybody,
I would like to know if it is possible to define the quantities of product by step (as in virtuemart 1.X) . For example, a lot of 5 units can be sold only by multiple of 5! (10, 15, 20) ? I try to find something with the custom field but nothing seem to work... Ideas or should I wait until a new release ? Thks for any reply
PS sorry for my poor english.
