Drag and drop between ExtJS tree panels with preloadChildren false

Question

I have two panels that get dynamically loaded. I need to drag and drop between them. The problem is that once I drag and drop an unexpanded node it doesn't get copied completely... just the node, not it's subtree (children). I don't what it expended in the first place because it kills the performance... I need to copy it unexpanded. Could that be done?

PS: Using ExtJS 4.1.
