I would like to be able to add data-transforms to PerfStack. For example, if a storage system tells me both Total Free Space and Total Used Space, I want to add a data-transform graph that takes those two and calculates % Free Space.
Or if i have a poller that gets total diskIOReads and Writes and I have a transform that gives me IOPS/sec, I'd like to put that transform on a PerfStack...
Found your question while looking into this. I think this might have gotten added.

monitoringlife, the type of transforms available in PerfStack today are analytical algorithms which allow for identifying things like anomalies or trends in the data. They cannot be used to perform mathematical formulas against multiple different metrics to derive a completely different metric. While that would be a pretty cool feature, I'm not entirely sure PerfStack would be the right place for it, as I can imagine use cases for things like alerting on those calculated values or adding them to a report.
