I've been running a single QuickBooks file for my LLC which has one rental property. I recently purchased a second rental property under the same LLC. I would like to start tracking transactions for each property under the LLC using classes. One class for one address and a second class for the other address. I have added classes and set up each property however. Now all my previous transactions show up as unclassified. Is there an easy way to automatically set all previous enter transactions to a default class given a certain date. Or a way to mass edit multiple transactions and set their class in one step? Can I avoid going back and editing each transaction? This would be a lot of work I'd like to avoid. Are there other solutions?
