the predefined template, for current stock, adds a more complex object than I need (i.e. I don't need opening land costs, etc). how can I define the template to use the object 'Opening Units - Social Housing'?
To define the template to use the object "Opening Units - Social Housing," you may need to modify the settings or preferences within the "Brixx - HousingBrixx Importer" program. Check the program's documentation or consult the support team for specific instructions on how to customize the template to suit your requirements.
