Replacing items {properly} after dispatch

@ThomasE,

Of course.
Many thanks for this quick slap!
Makes total sense.

I am definitely weaving the data (preferred) instead of replacing indices now :+1:.

Sorry for confusions, sifting takes place earlier in the process. The current data set gets unflattened and recombined, after this ‘dispatch’ operation, with its parent process:

Nonetheless I will definitely revise this sifting precursor.

Thanks again!
