I think the easiest way would be to use a snippet that integrates Wayfinder.
Then use a template that creates a list, maybe like this:
[+wf.title+]==[+wf.link+]||
Then return the results to your TV, with something along the lines of
@EVAL return $modx->runSnippet('getIDs',array('startId'=>'10'));
in the "Input Option Values" of your TV.
I’ve never done this, but I can’t really see why it wouldn’t work. An alternative maybe to use
http://modxcms.com/getdocumentchildren.html
in your snippet as opposed to wayfinder. Hope these ideas are of use to you.
