One thing which happens quite frequently, is that the clients that we work with that work out of specific depots are looking for staff, so once we have a shortlist of interviews, I begin to arrange them however whenever I click "Client interview" it assumes it is going to be held at their head office (company location).
Along with my previous request of unlocking the location tab, I think being able to choose a site/depot for an interview will be held at would be useful.
So when you're arranging an interview you have the option of using a site address for interview, or you have the second option of using a text box, where you can freely enter the address if it differs to the site.
