jQuery Grid Plugin - jqGrid

Hello

I was wondering if it would be possible to extend the region at which a row could be "dropped" into another table? Currently the event only triggers when the exact center of the dragged row is within the actual grid cell data. I feel that this can be a bit restrictive, especially in the scenario where the target grid is empty. Enlarging the region for which the dropped event fires would be very helpful for many users.  Even if it just included the white space within the grid would be an improvement though I don't see why having the entire grid area fire the event become problematic. 

This can be demonstrated on the 3.6 Drag and Drop Rows demonstration page.
