How does one report across forms?

My specific use case is that I have two forms. One captures attendance (hours worked) for employees while the second captures work performed. Both forms have user field and date field, which ought to be sufficient for cross-reporting.

There seems to be no way to do this in Creator, and only half-baked ways to do it in Analytics.

There is documentation that this feature used to be available in Creator as "Combined Reports" (link), but I see no way to achieve this outcome in the current version of Creator.

I've tried to do this in Analytics, but it doesn't appear to be capable of figuring out that a date in one Creator table is the same as a date in another Creator table without me doing a bunch of programming. For some reason, Analytics also appears to not be capable of reflecting current Creator entries, instead requiring a sync that can't be done more than once every 3 hours.

Am I missing something, or is Zoho really incapable of doing a fairly basic reporting task?
