PNA Guided SMC cal source sweeps for fixed frequency I/O

I have just started running guided SMC cals with a large number of sweep points - I noticed that two source power sweeps are required by recent firmware even if the input or output is a fixed frequency. If the number of points is small, it doesn't matter too much but for high resolution sweeps, it really extends the cal process. Is there something hidden that I am not seeing or is the PNA just repeating the same measurement and placing the result in multiple memory locations? Could the firmware be updated to simply copy the result of a single measurement to multiple locations (or better yet simply use one location instead of one for each sweep point)?
