Q: how I can state my address by placing a pushpin on the maps of ios 8

1)I want to state my home address on the maps of my iphone 5s ios 8.1.1 to use the reminders options at location (my location). My road is not named at the maps because I live out of town, so there is not address that describes my home.

2)Also, sometimes I need to place a pushpin to a place that has no address on the map, to remember something to do when I reach there.

How can I do that ?

3) Can I do that on My Mac reminders? I see no maps there when it prompts me for the location, only contact or address....
