Daniel there are various ways to implement this. But the cleaner ways will require some developments.
The easiest way would be to use the start parameters passed via the URL to the application, and then force a reload. see the docs at http://svn.pmapper.net/trac/wiki/DocManual#Extentreadfromlayerfeature: If the configuration for PHP sessions in php.ini is set to use cookies for the sessions, then the application should keep all existing activated layers after reloading. You could try testing this first with 2 or 3 URL's and see if this is providing the functionality you need. eg. adding the strings to the normal URL after the "?" &zoomLayer=regions&zoomquery=regionn...@1@regio...@0@0 &zoomLayer=regions&zoomquery=regionn...@1@regio...@0@0 &zoomLayer=regions&zoomquery=regionn...@1@regio...@0@0 for description see link above. If this does the job for you, I can give you some advice how to implement this eg. in a plugin similar to the 'mapselect' where you create an option pick-up list. You need to find a way to specify the regions in a list. If there are not too many one could put this in a simple text structure and read the information from there.
