In Excel adding new office information to a report is done via the Insert Option. Scroll down to Office Details and select the items to be added to the report.
To add the Project/Office Image select the item from the Insert menu also.
Note: The image which will be displayed will always default to the Project Image saved not the Office Image. There is no selection mode for Excel.
Much like Template Studio existing template images can still be added via the Template Image item in the Insert Drop-down.
When the report is run it will now display the logo and the office information added.
