Is it possible to change the default week format?

[lucharo]

Hi, I often use the date modifiers (week, date, yearmonth, yearweek, utcyearweek etc) I noticed that the week starts at 0 instead of 1. I also notice from https://vega.github.io/vega-lite/docs/timeunit.html that week returns sunday based weeks rather than ISO week number. Is it possible to change this? It'd be very useful

If it's not possible to change it what alternatives do you suggest? Calculating week number with a dataframe operation before plotting?
