Specific time signature

Hi everyone !

I need some help, I can’t find how to write this kind of time signature in Dorico.
It seems that Dorico don’t want to understand that I want dotted semibreve as denominator…
I hope you can understand me ahah

You can easily change denominator in the properties panel.

Ah, Carmina Burana…

Do your musicians a favor and use standard time signatures.
