Should your site cover a large geographical area or you would like to distinguish different property types you may do so in the following way.
There is already a pre installed site plan in the data folder 'Building_Plans' , to add a second simply open this folder and add the new image (in the designated file format of course) and save this as 'Siteplan2-VXA.PNG' .
To then change between plans on the home screen use the small arrows to the right hand and left hand side of the image.
You can alternate between these views easily as an when needed.
These images can be changed at any time by simply overwriting the file with the designated name.
