I've been using the Google map's star feature for this type of address transferring - star a location on PC and it will show up on your phone in seconds, you just need to unstar it later if it's not an address you want your map to remember.
I don't even need to star anything. If I type an address into maps.google.com on my PC, as long as I'm signed into Google it will be in my Maps app search history.
