Manually add a tagged location that is not a previously visited location

Currently, you can only tag a location from a previously visited address, per my use experience and the topic here. 

I would like to be able to add a location before I visit it, so I can set my sleep behaviors prior to arrival. I often don't have time or forget when I arrive and consequently get an unwanted behavior. 

Right now I have to go back to a location that I haven't tagged and use that to tag a location that I haven't visited, but that often requires lots of panning and zooming in/out on the map. 

It would be nice to have a button on the tagged location page that opens up a window where you can search for an address and then add the location. I think this could be accomplished fairly simply by adding a map search field to the add tagged location page.

Thanks!
