Kind of irregular meter, how can I achieve this measure division?

Hello.
I have some 4/2 measures and I want to avoid using breves when they fill the measure. I’d rather use two tied whole notes. For that, I typed [2+2]/2


and set these notation options:

What am I missing?

Dorico doesn’t consider 4/2 to be an irregular meter, I’m afraid, even if you specify [2+2]/2, because all (both) of the beat groupings are the same length. I don’t think Dorico has a notation option that would allow you to force a note that fills a complete compound duple bar to be split in two.

Ok, I understand, Daniel. I’ve made a macro to change them one by one. Thanks!
