How do I make NEB table macro use detrended, normalized ref fluxes?

We're part of the TESS followup program and are using AIJ to analyze light curves of TESS exoplanet candidates.  We're practicing on TESS targets that have been retired from the candidate list because a nearby eclipsing binary (NEB) was identified as responsible for a false TESS detection.  

We remove noisy stars and detrend as usual, and get light curves flat to RMS~2 ppt.  We clearly see the NEB signature in the correct star's (T2 in our case) light curve.  We save new columns in the data table with normalized de-trended relative fluxes, e.g. rel_flux_T2_dn, and errors.

But when we then use the nifty AIJ "Create NEB search reports and plots..." tool, it seems to grab only the NON-detrended, noisy light curve data.  The resulting plots are not flat at all, and fail to identify the NEB that we can see pretty clearly in the detrended normalized curves in Multi-plot.

Of course we don't need the NEB tool if we can see the NEB by eye.  But we certainly want the NEB tool to use the best, flattest, lowest-noise, detrended data when we do use it.  But how?

I'm probably missing a simple step in there somewhere -- thanks for any help identifying it!
