PNF Box Dates & Renko reversal size

First of all my big appreciation to Daniel and all other contributors for this great resource!

I have a request regarding the 'pnf' resp. 'renko' chart:

1) Is it possible to include to the return_calculated_values an additional array, that contains the dates for each box (e.g. pnf_box_date), that is matching the pnf_values? I guess it can be created easily in the same step when the pnf_values is processed.

2) I tried to get the dates from the renko return_calculated_values, but since there is no reversal size considered and therefore not equivalent to the 'pnf' chart, it was not possible. This would lead to my 2nd proposal to add reversal brick according to the 'pnf' logic.

Locate the PNF and Renko calculation entry points that produce return_calculated_values and pnf_values. First trace how box or brick values are assembled, then verify that returned dates align with PNF values and that Renko reversal size follows the requested PNF logic. Done means both requested outputs are available and their alignment and reversal behavior are covered by checks.
