W2H does not currently have a way to add a location to a shift. You can type in an address or add an HTML link to a map into the shift description when you add or edit a shift, or to multiple shifts in a week on the SCHEDULE>Grid View.
You also can add locations or map links to the Bulletin Board or weekly schedule notes or the Helper Homepage Notice.
Be sure any use of HTML only includes single quotation marks.
add address to the details of the shift, location events, multiple job sites that each helper has to travel to google map, address linked to a shift for that job location
