moderncv: how to change the separator between address and city

Question

I'd like to know how to change the separator between address and city in moderncv theme\moderncvtheme[blue]{casual} you can see in the figure further down. I know the bullets can be modified by \footersymbol but this does not affect the hyphens above. And so far I did not find a solution. I'd like to have the hyphens replaced by the bullets. Would anyone help, please.

\documentclass[12pt,a4paper,sans]{moderncv}

\moderncvtheme[blue]{casual}

\usepackage[ngerman]{babel}

\usepackage[T1]{fontenc}

\name{John}{Doe}
\title{title}
\address{street and number}{postcode city}{country}
\phone[mobile]{+1~(234)~567~890}
\phone[fixed]{+2~(345)~678~901}
\phone[fax]{+3~(456)~789~012}

Edit 1:

I modified the suggestion by Torbjørn T. which gives me the following result:

I replaced [~\textbullet~] by [\footersymbol] adapting the different spacing between the bullets in the first and the following lines. Simultaneously I was able to modify the bullets color globaly by \renewcommand*{\footersymbol}{{~~~{\rmfamily\textcolor{color1}{\textbullet}}~~~}}. As far it is exactly what I want, even a bit more ;). Thanks for your help :)

Answer 1

The dashes seem to be 'hardcoded' in the \makecvfooter macro. Below I copied the definition of that macro from moderncvstylecasual.sty and changed ~--~ to ~\textbullet~ in two places.
