[pstricks] using braces from pstricks-add

I'd like to use psbrace to mark stages in a flowchart.
However, there are two problems that I couldn't solve in a clean way...

1) I didn't find a good way to set the start- and end-points of the
brace, except using pnodes in a separate psmatrix column and guessing
the correct offsets. (See my example below.)

2) The brace and it's text-label doesn't eat up space so its width isn't
included in the width of the psmatrix. Thus centering the whole figure
won't work.

Are there any good workarounds for those problems?

    \pnode(0,0.5){X1} & \dianode{S}{Condition1?}\\
    \pnode(0,-0.5){X2} & \rnode{SA}{\psframebox{do something}}\\
    \pnode(0,0.5){Y1} \pnode(0,-0.5){Y2} & \dianode{R}{Condition2?}\\
    \psbrace[ref=r,rot=180,nodesepA=-8pt](X1)(X2){Stage 1}
    \psbrace[ref=r,rot=180,nodesepA=-8pt](Y1)(Y2){Stage 2 very
      looooooong text}
