Search for assets without warranty info

Valued Contributor

Does anyone know an easier way to do this than my method below? The only options I have are before or after a date, or more or less days. There's no way to search for a null value.

My only thought is to get the S# of the machines, drop that in a spreadsheet, and put a dummy value in a new EA, then upload that using the API with MUT. Then I can search for those assets, and tell the JSS to check GSX for their warranty info.

But that's a lot of work for something that should be easy. :(
