st: Two baselines in stpiece

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.
