Sorting folders in K2DocAttachment component

Hi,

I've got a process where a user needs to select a folder for uploading file using K2DocAttachment component on the form. The problem is SharePoint library has more than 50 different folders and they go unsorted that make it not very comfortable for the user to search the folder he needs.
Is it possible to sort the list of the folders in K2DocAttachment folders area and how?

Thanks!
