Adding folders to the toolbar?

Good day. Don't have a lot of experience with Draftsight, so would like to know about this specific issue. 


I want to ask if it's possible to add quick access folders to toolbar in DraftSight, so that a user would be able to click and import blocks from several chosen folders on the PC. What I mean is, for example, being able to put function on the ribbon that allows user to click panels named "Folder 1", "Folder 2", etc., and gain access to specific folders in order to quickly import blocks from there, preferrably with blocks previews. I would like to know if it's possible at all, and how. Thanks in advance.
