Chords with multiple glissandos

[David Stocker]

Is there any way to make this work, so that both sets of notes are 
connected with glissandos?

**minimal example**

\version "2.13"

\include "english.ly"

\paper {
 ragged-right = ##f
}

\relative c'' {
 cs1
 <<
   {cs4 \glissando b \glissando cs2}
   {gs4 \glissando fs \glissando gs2}
 >>
}

**end minimal example**
