st: FW: stcrreg: when the proportional hazards assumption fails

Hello All,
I am wondering what options are available when the proportional hazards assumption doesn't hold in a competing-risks regression. The assumption holds for my main independent variable of interest, but not for another (ordinal) variable that I'd like to adjust for; fitting it as a time-varying covariate gives a significant result for 2 of its 3 levels.
I could get around this by stratifying by this variable in a standard Cox model, but this doesn't seem to be supported (yet) by stcrreg.
Are there any alternatives?
Regards,
Zoe.
