sorry I thought of \pcline but ...
With a little modification ist is possible:

\def\NCLine{\pst at object{NCLine}}
\def\NCLine at i{\check at arrow{\NCLine at ii}}
\def\NCLine at ii#1#2{%
   \pst at getcoor{#1}\pst at tempA
   \pst at getcoor{#2}\pst at tempB
   \use at par
   \psline(!\pst at tempA\space \tx at UserCoor)(!\pst at tempB\space 
\tx at UserCoor)
