Using RQM with a large number of execution environments

I have a situation where a QA department needs to test 1000 manual test cases on 25 unique device environments for every iteration. At first blush, in order to get the fine grained reporting about which test cases fail for which device, they would need to create an execution record for all 25 devices across all 1000 test cases, or 25,000 execution records. And then of course, during testing they would need to go update them all manually. The testing they perform is such that they can test multiple devices concurrently. Meaning, they step through each test step on each device in the same sweep through one test case. Is there any way to limit the number of execution records, but still maintain pass/fail infomation for each platform/device?

I would think this would be a common usage flow in any embedded systems, or device production.
