Triplet beaming help

[Mark Probert]

Dear Wisdom,

In the following snippet the beaming behaviour depends on the beat 
structure, but I haven't found a way of making B beam in the same way 
as A (I want to separate the joined triplets). Any suggestions?

TIA 
 .. mark.

  r4^"A"  \tuplet 3/2 { d8 d d } \tuplet 3/2 { d8 d d } d8 r8 |
  r4^"B"  r8 \tuplet 3/2 { d8 d d } \tuplet 3/2 { d8 d d } d8 |
}
\score { \new Staff \tune }
