Hi,
With the current interface, that is not possible.
If you want to add such feature it will require some custom development in order to add the button in the toolbar and also to add the related function into the controller.
I can create a feature request ticket for HikaShop (and HikaMarket) ; we already have some tickets for the improvement of the order management. But regarding the current developments, I could not provide you any schedule for the implementation.

By the way, do not send me private message, use the "contact us" form instead.
