How to drag and drop multiple samples into Battery 4 kit in columns ?

 
 
As the title suggests, dragging and dropping multiple samples into an empty kit in Battery 4 loads the samples into rows. 

But I want them to be loaded into the columns, not rows, in some instances. 

As an example, in an 8 x 8 empty kit grid, if I multi-select 8 samples from the browser and drag them to the first cell A-1 and drop them, they get loaded into the row A under columns 1 to 8, that is, into cells A-1 to A-8. 
But instead, I want them to get loaded under column 1 against rows A to H, that is, into cells A-1 to H-1. 
I tried the key modifiers like Ctrl, Shift, Alt when dropping but does not work. 

How can I achieve this ?
 

I checked my Groove 3 tutorial as well.  
All I could find is that if you load multiple samples, they align in a row. 
Like RBH said, you may have to manually move them to columns.
