settings.xml: profiles do not allow defining mirrors

I use Maven either in my office or outside my office.

At work we have a repository manager thus we have mirror properties in the settings.xml for the whole teams global settings. We also have a defined a number of repositories in our work profile so we can mirror these to different repo's managed by Archiva. Now when I work from home I have to comment out the mirror definitions and activate a home profile which does not define any repos so Maven just goes out to the WWW as normal. So the pain is having to comment out and un-comment the mirror settings every time I go from work to home and visa-versa.

Can we not have the option to add mirrors inside profiles?
