repeatTie question

[Eby Mani]

Is it possible to specify "minimum length" for it so the repeatTie appears to 
connect the previous note on another voice.

e.g.
vOne = { ees4. ees8 c'4 aes }
vTwo = { d4 c ees2 \repeatTie }

I've tried vTwo = { d4 <<c4 \hideNote ees~ >> \unHideNotes ees2 }, but this 
will hide both "c4 and ees", leaving the tie visible. And "ees2-\tweak 
#'minimum-length #10 \repeatTie" doesn't have any effect. Any suggestions ?.

Thanks.
