Shouldn't it be possible to add several locations?

I'm trying to use RTM out of context, but it gets a little confusing when I have to use both lists and locations for context.

The reason why I want the ability to add several locations, just like tags, is because I have a computer both at work and at home. The cold medicine could be bought at both the local pharmacy and the pharmacy close to my subway.

If I can get several locations, I would be able to look up at the "near me" function at my cell phone when I am at a place, and then remember to pick up something.
