Hi all upon advice from Andreas, I started a formal description of the requirements for such a feature:
https://docs.google.com/document/d/1cDemM2m88_mbs65sYzfBbVdHI_ObOjf_i35ne3OKsRs/edit?usp=sharing Please, anyone interested, do check, comment, add, correct,... Once we have a "final" version, I will inquire a more precise financial estimation. Then let's see how we can move forward!
