Automatic beaming split in C time signature

Bar 1 of the attached file shows how I need beams to be split. Bar 2 is the Dorico default. I have tried, and failed, to cause the beaming to be automatically split in subsequent bars like it is in bar 1 – which was achieved manually. I am probably missing something – or is this not possible with C time signature?

See this screenshot (which shows the relevant setting in Notation Options)

Thank you once more. I had been trying to use shft-M and [1+1+1+1]/4 without success: https://steinberg.help/dorico/v1/en/dorico/topics/notation_reference/notation_reference_note_rest_grouping_custom_t.html and it is not clear to me why it didnt work in this case.
