Add number to suggested street??

When I start typing the name of a street in maps, i get suggestions accordingl. But when I choose one of the suggested street It automatically shows me the way to that street. Now I want to type my specific number on that street but the address field is already locked.

so now I have to type my whole address again, not tapping the suggestion, just to get to type my numnber at the end. Very annoying.
