We are also able to accommodate TSV feeds to add properties. If you would like to set up a TSV feed, follow this link to see the feed specifications: github.com/luxre/knowledgebase/wiki/TSV-Feed-Spec.
Once your file is ready, send it to firstname.lastname@example.org and someone from our web support team will test it and correspond with you on how to move forward. We are not able to create the feed for you, but web support is available if you have any questions.
If you are unable to create a TSV feed, you may manually add properties via the Luxury Lounge. See How do I add a property manually?
