This is good, and helpful, but I was wanting two beams between the groups of 32s, not one. [Maybe this is non standard after all.]

Ah my apologies; I misread your mail. A quick search didn't yield what property sets the default at one beam for subdivision. Without changing that your best bet would be to make a function that does what you wrote automatically. I'm not good at writing music functions, but below is one I just hacked up. It only works when there are 10 notes in the tuplet, but it should illustrate how to do it. The proper way would probably involve specifying a music-list of notes and working on that. Someone else might best know how to do it.

\version "2.18.2"

tenTuplet =

#(define-music-function

  (parser location note1 note2 note3 note4 note5 note6 note7 note8 note9 note10)

  (ly:music? ly:music? ly:music? ly:music? ly:music? ly:music? ly:music? ly:music? ly:music? ly:music?)

  #{

  \tuplet 5/4 { #note1

  \bl #note2

  \br #note3

  \bl #note4

  \br #note5

  \bl #note6

  \br #note7

  \bl #note8

  \br #note9

  #note10 }

  #})

bl = \once \override Stem.beaming = #(cons (list 0 1 2) (list 0 1))

br = \once \override Stem.beaming = #(cons (list 0 1) (list 0 1 2))

\score {

  \relative c'' {

    \time 1/4

    \tenTuplet e,32[

      c'

      bes

      e

      d

      bes'

      g

      d'

      d,

      aes']

  }
