Add "Location" to .ics file in Approved appointment calendar invite#1458

Right now, even though we filled address in “Setting>Company” properly, no location is shown in the Calendar event attach to Approved appointment notification :(

I think this if a low hanging fruit: very easy to fix (small modification of .ics file creation), and it will bring real value to customers :)

I would like to modify this one: I found out that this actually works in a way, but not the way it really should… Amelia actually adds Service location name to Location field of the invite… From my point of view, it should add the Service Adress into location field to properly guide the customers to correct address.
