Add button or way to export Sitemap only

Title pretty much says it all. Would like to be able to export only the Sitemap without having to export any pages or overwrite anything in my export directory other than the sitemap. Would be great if the export dialog would also ask for a location for exporting it so it doesn't go in the default export directory. Maybe a checkbox to export to default directory and when we want it separate we can uncheck that box? Dunno, just would be nice if I didn't have to do a lot of prep just to export that file.

Thanks for the suggestion! We can make some kind of custom export, which lets you choose files to export from a list with checkboxes. The sitemap will be one of the files in that list. Do you think this would help in your case?

That would be more than perfect and solve multiple suggestions by others too!
