Token for current calendar week

I would love to use a token with the [current calendar week ] for the Subfolder  in the "Export Cross Recipes Tokens tool" so that I am able to export my images into a subfolder called like this: CW[current calendar week]/[imagename]

( for example CW29/bananas/ )

I could not find anything in the Capture One 22 (15.3.): could you make this available in a future release?

Best
