[pmwiki-users] further intermap recource

[noskule]

hi list
how do I add a further intermap recourse to pmwiki. In pmwiki.php it is 
defined: 

$InterMapFiles = array("$FarmD/scripts/intermap.txt",
  "$FarmD/local/farmmap.txt", '$SiteGroup.InterMap', 'local/localmap.txt');


cause its not SDV( ) I cant predefine it. I would like to add some Intermap 
destinations to my skin on a page like NetstreamsSkin.InterMap. The links 
defined here sould affect all groups.

thanks for any hints
