st: Two baselines in stpiece

Hi,
I'm using stpiece (or streg) to fit piecewise constant models. I'm
wondering whether it is possible to have separate baseline risks for
two groups of observations (say, dummy Group).
Fitting separate models for the two groups doesn't work because I
should perform tests of statistical significance for interactions
between Group and other covariates.
