Bookmarks/Marker Sets type of functionality?

I've been exploring different IDE's and netbeans looks really really close to what I want.  There is one
feature I'd really love to see, and I finally found an implementation in another IDE, which makes it easier
to describe what I want.

In JEDIT the plugin is called MarkerSets
http://plugins.jedit.org/plugins/?MarkerSets

Basically, you can maintain a list of line numbers and files in a "set" and by launching/opening the "set"
you open all the files to those line numbers.

Even more importantly, you can export that marker set to an XML file.

From my perspective, the use is if I am editing a "bug" and I edit 4 files, I can create a marker set of the first
line changed in each file.  Than when I'm done, export that marker set to an xml file and attach it to the issue tracker.

Then if someone has to come back later and work on the same code, they can get the marker set off the tracker and
open all the files automatically.

So, does Netbeans have any similar functionality/plugins?  If not, how hard would it be to add something
like this and what would it entail[ie can it be done in  a macro, does it require java, etc?]
