invisible slurs in tablature

[Grammostola Rosea]

Hi,

I want to get invisible slurs in tablature... how?
This is my score:



\header {
 title = "BLUE BOSSA"
 composer = "K. Dorham"
}

global = {
 \key c \minor
 \time 4/4
 \partial 4
   \override TabStaff.Stem #'transparent = ##t %% Makes stems transparent
\override TabStaff.Beam #'transparent = ##t %% Makes beams transparent
\override TabStaff.Dots #'transparent = ##t
\set TabStaff.minimumFret = #3

}

chordNames = \chordmode {
 \global
 % Akkoordnamen volgen.

}

jazzGuitar = \relative c' {
 \global
 % Muziek volgt hier.
 g4\4 | g'4.\1 f8\2 es d4 c8\3(  c2.\3)  bes4 as2) g'4.\1 f8\2( f1\2)

}

chordsPart = \new ChordNames \chordNames

jazzGuitarPart = \new StaffGroup \with {
 %\consists "Instrument_name_engraver"
 %instrumentName = "Jazzgitaar"
} <<
 \new Staff \with {
   midiInstrument = "electric guitar (jazz)"
 } { \clef "treble_8" \jazzGuitar }
 \new TabStaff \with {
   stringTunings = #guitar-tuning
 } \jazzGuitar
>>

\score {
 <<
   \chordsPart
   \jazzGuitarPart
 >>
 \layout { }
 \midi {
   \context {
     \Score
     tempoWholesPerMinute = #(ly:make-moment 100 4)
   }
 }
}
