Is there a way to change how Citoid locally handles date formatting when you automatically add a citation from an URL? By now it adds ISO 8601 dates (YY-MM-DD), but the Portuguese Manual of Style recommends that dates should follow "dia de mês de ano" (16 de dezembro de 2016).

You could change the template logic as suggested by Citoid/Enabling_Citoid_on_your_wiki#Access_date_is_formatted_differently_on_my_wiki. Right now I can't find a task or example with actual instructions about that, sorry.
w:en:Module:Citation/CS1 at the English Wikipedia supports this. If you've got current versions of these templates, then use |df= to set your preferred date format. You can adjust the templates to do this automatically/in all cases except when locally over-ridden.
The current pt-version does seem to support |df=, but I'm afraid if I try to correct it myself, I'll end up doing it wrong and breaking everything.
I wonder if User:He7d3r or User:Dbastro would like to look into this. Since the code exists, it'd probably be good for the Portuguese Wikipedia to make the most desirable format be the default anyway.
