Can I add a GeoRSS or kml and show it also on the maps?

Hi,

thanks for your great plugin. I'm trying to develop a blog with it.

I was wondering how can I "combine" the locations in wordpress database with other sources and show them together whenever I put INSERT_MAP on a single post , or when asking for INSERT_GEOPRESS_MAP for displaying all locations.

The idea is to be able to show not only that point from the post, but to have the context.

My blog focus on a biketour project that happens every year
http://blog.ecotopiabiketour.net
In my case I want to show the place to which the post refers and also the route and other important points.

For now I would like to combine the kml that comes from a mymaps:

Thanks for your time,
