I'm currently running three sites, each of which requires fairly frequent updating and therefore each time I change sites, I need to:

a) open the correct *.web file and after making the changes save it.
b) remember to change the directory when I export it if it's not the same web site on which I last worked.
c) remember to change the publish details in website properties.
Needless to say on the odd occasion I've screwed up and added a whole bunch of files from one of my sites to another.

Is there any way of updating b) and c) when I load up the site?
Many thanks
