Thanks for all your comments and votes.
This is possible if you make the category field required and single choice. Your new item created will then have the status set automatically as new.
Another option could be to add a calculation field and use this to set a default value, when the item is created. You can see more info on the calculation field here https://help.podio.com/hc/en-us/articles/201019358-Calculations
We do not have a finished solution for setting all fields as default, but the calculation field can make it possible to some extend.
Thanks again for all your feedback and support.
