Side bar - create navigation links to all parent folders on another space

[Stacy Allotta]

Hi, is there a fast way to link to all the content on another space and have it display on the side bar?  Other than creating the links to each parent folder manually, I mean. 

I essentially need to put the "page tree" macro for another space in my side bar. I don't even know if you can put macros in a side bar by the way.  Thanks in advance!
