When I lodge a new enquiry it would be good if the map could zoom to the area of my previous job. Most of the enquiries are in a similar area and it will make it easier than having to search by address every time.
I like the idea, but maybe instead you could show the outline of your previous DBYD submissions, maybe as a layer that could be turned on/off. If the outline was selectable we could easily and quickly resubmit certain areas.
This would also help in splitting up larger submissions into smaller areas if I could see the outline of my last submission I could ensure that there is no gaps and minimal/no overlap
