Change beam property on the whole score

Hey lads,

So I'm arranging this one song from Coldplay "Clocks" and as you might know, it's in 4/4 but the rythm is grouped as this : dotted quarter note ; dotted quarter note ; quarter note.

Hence when writing down the arrangement, I'm supposed to group the eights notes as following : 3 - 3 - 2

Problem is : the default notation is this : 4 - 4

I know that I can change beam properties bar by bar but since this rythm is in all the song, I was wondering if I could input the rythm somewhere in the settings so I don't need to rework the beams anytime I write eights notes.

And if this feature isn't available, it would be swell to have it.

Thanks in advance for the responses.

P.S

The images with this are what I mean by "grouped as 3 - 3 - 2".
