How to track distinct module usage in the Sentinel License Manager and WlmAdmin tool

I'm using IBM SPSS Statistics with a network license. Everything's installed, authorized, and seems to running properly, but I've got a question about the WlmAdmin Sentinel License Manager display and logging. I know that our organization has licensed Statistics Base and several other modules, and we received a single license authorization code that I assume had all the various module authorizations bundled together -- and the users do get access to all the modules we're supposed to have. The problem is that only a single 'product' is shown in the License Manager display ('0' or '1200') and I can't track individual usage of the various other modules any more finely than that. For instance, we've got 10 users license for Base and Trends, but I've got a feeling that given our current usage levels only a maximum of 5 people are actually using the Trends module functionality at any given time. If I could confirm that by checking usage reports, then I could reduce the number of licenses we pay for. Is there some way I could track distinct module usage?
