NEED: Tree alignment of Protein sequences

Let me explain what I meant with "tree alignment":

Given a phylogenetic tree, you may calculate a multiple alignment. 
But I need the ancestral sequences be calculated as well, i.e.
the inner nodes of the phylogenetic tree must be labeled as well :

                 root ALWVG   <----------------------------
               /            \
            AL-LL  <-      LLWVG   <-
           /     \        /     \
        AL-LL   GL--L   LLWVG  LL-VG

Now the corresponding __tree alignment__ is

ALWVG (*)   <-----------------------------------------------
AL-LL (*)   <-
LLWVG (*)   <-
AL-LL
GL--L
LLWVG
LL-VG

where "<-" indicates reconstructed sequences. (artificial example)
