E4440A PSA series SCPI question

Had a quick question that I've been wondering about for a while now. Down in my lab, we're moving from E4407B ESA-E series of SpecAns in our automation system to the E4440A PSA series. We're looking to update the automation software accordingly, and thankfully most of the SCPI commands between the two platforms are identical.

One thing that's been bothering me though: the E4407B ESA-E series has a lovely command called "Query the Signal Peaks" (:TRACe:MATH:PEAK[:DATA]?) that returns alternating amplitude/frequency pairs on trace1. This is far more convenient than doing a Peak Search for the marker, querying the X value, querying the Y value, then doing Next Peak and repeating.

Is there any command on the PSA series of SpecAns that might accomplish something similar? I haven't found anything in the User's and Programmer's Reference yet, but it's completely possible that I've overlooked something.

Thanks in advance!
