Separate “Local Lock Suspension Time” from “zIIP on CP Time”

We have been in the process of activating and evaluating SMT-2 across several LPARs.  As part of our analysis and IBM’s analysis (TS015958511), we were made aware that "Local Lock Suspension Time”, which is not eligible to run on a CP, is always a part of “zIIP on CP Time”.  As a result, this makes it difficult to quantify how much of “zIIP on CP Time“ is genuinely eligible to run on the CP.  

 As a request, we would like to see "Local Lock Suspension Time” be reported separate from “zIIP on CP Time”.

    Local Lock data is reported as part of Postprocessor Serialization Delay (SDELAY) report (XML only, requires SMF 74.5). Please take a look at figure 2/table 2: https://www.ibm.com/docs/en/zos/3.1.0?topic=report-serialization-delay-details . Would this Local Lock data work as an answer for your request?
