We just launched new updates to our Repair Estimator tool that adds in new functionality to duplicate entire categories in the Repair Estimator.
Category duplication will be especially useful when estimating rehab costs by room.
For example if you have a property that has 3 bathrooms, you could estimate the costs for the first bathroom and then duplicate the category to recreate the 2nd and 3rd bathrooms with the exact same repair items, quantities, prices & descriptions.
