Get Monte Carlo Nominal Data in ADE XL

in ADE XL I am running monte carlo and would like to make measurements against the nominal simulation. That is, I want to do something like f(current_iteration)-f(nominal). How can I access the nominal data in ADE XL for use in a measurement? I can get the data with something like v("/netname" ?result "nom_dc-dc" ?resultsDir <path_to_nom_psf>) but this requires hard coding the results directory. I want to have something I can put in an expression in the Outputs Setup tab that automatically picks up the current monte carlo's nominal data.

There appears to be a separate psf for the nominal data that is different than the main psf that includes all of the mc iterations. Currently, I'm trying an OCEAN script type output to get the current run path and from that build the path to the nominal data for use in v() function. My OCEAN uses axlAddOutputs and axlOutputResult to get the waveform in the ADE XL outputs list. The body of the OCEAN gives the desired result when copied into the CIW but ADE XL Results tab gives "eval err." My best guess at this point is that re-running outputs from the Results tab doesn't like axlGetCurrentHistory.

ADE XL appears to only use the nominal simulation to determine if there's an error before continuing with the monte carlo run. There doesn't seem to be any way to get the nominal data back into ADE XL. The OCEAN script method above is just what seemed like it would work and is my latest attempt. It feels like there should be something simpler and more convenient... as in, ADE XL should actually be aware somehow of the nominal data.
