[racket] Arrows in DrRacket

Is there any way to use syntax properties or anything like that to tell DrRacket where to draw the arrows to?  

I’m trying to make my own language and I wanted to be able to have DrRacket draw the arrows.  

Also is there a way to have it draw multiple arrows, so that for example it would draw arrows not only to the original definition but also to all of the expressions that set! it?
