Here's a hack using the trick detailed in the LSR for aligning
dynamics (http://lsr.dsi.unimi.it/LSR/Item?id=200):

#(define RH rightHandFinger)

#(define (my-stroke-finger::calc-text grob)
   (let* ((digit (ly:event-property (event-cause grob) 'digit))
          (text (ly:event-property (event-cause grob) 'text))
          (finger (vector-ref (ly:grob-property grob 'digit-names)
(1- (max (min 5 digit) 1))))
          (direction (ly:grob-property grob 'direction)))

     (if (string? text)
         text
         (if (= direction 0)
             finger
             (make-combine-markup (cond
                                   ((= direction UP)
(make-transparent-markup "p"))
                                   ((= direction DOWN)
(make-transparent-markup "i")))
                                  finger)))))

\relative c'' {
  \override StrokeFinger #'text = #my-stroke-finger::calc-text
  \set strokeFingerOrientations = #'(up)
  <c-\RH  #1 >4 <c-\RH #2 > <c-\RH #3 > <c-\RH #4 >
  \set strokeFingerOrientations = #'(down)
  <c-\RH #1 > <c-\RH #2 > <c-\RH #3 > <c-\RH #4 >
}
