Hi Guys, I do not see it is possible without Python code. The function  def _report_custom_engine_aged_payable calls the function def _aged_partner_report_custom_engine_common and this function built the select. However, the selection is hard coded. Then the result of the selection is converted into a dictionary and the key of the dictionary is the subformula.

Hola, llevo mucho tiempo intentando hacer lo mismo, pudiste hacerlo?

hola david, yo también quisiera agregar más columnas con más fechas de vencimiento. Pudiste encontrar como se agrega?

Hi David:

A lot of the Accounting Reports cannot be modified through the Accounting Reports configuration since they use something known as a "custom handler" which is essentially a bunch of python and javascript code that is specific to that report. The Aged Payable report is one of them. Since the field appears in the v17 version, you may want to check with Odoo support whether there is a plan to backport it to v16 in the near future.
