I think right now the only way to do it manually:
Export member list in Excel format, remove everything you do not need.
Use one of the mapping utilities you can find online - importing the locations file you prepared. (I am not an expert on these apps but I have come across a few in the past)
I know I have come across a few clients who did that but I can not find them now, I will post a link if I find them.
