Mass Import data in the order fields

Hi All! I am still pretty new to IS but I am getting there… Is there a way to do a mass upload to orders? I have about 400 records that I need to mass update the exact same information. All of this is in orders… not contacts.
In simple terms - I need to indicate that an order was paid on a specific date (10/1/17). But there are 400 orders. Is there a way to do this easily?

Thank you all!

There is a set of “restricted imports” that you can ask Infusionsoft support to enable. This allows you to import a few types of data that you wouldn’t otherwise be able to.
