View - All Cases Resolved on the first day they were opened

Hi,

Am trying to create a view which shows all cases that were resolved on the first day they were opened.

Seeing as the case doesn't have a resolved on date field, and the only way to get at it would be to use the case resolution activity. But not being able to compare two entities even with a calculated field, there doesn't seem to be an easy solution without using code.

Any suggestions welcome?
