st: Dunnett's P-value and negative binomial regression

Dear Statalist,
The command -pwcompare trt,mcomp(dunnett) effect- is not allowed after -nbreg- or -stcox- because of the dunnett method of comparison. dunnett is only allowed with results from anova, manova, regress and mvreg.
The R package multcomp allows the dunnett option for generalized linear models and Cox models, however I would prefer to use Stata.
Is it possible to use Stata to estimate dunnett P-values and confidence intervals after a negative binomial regression?
The dunnett method compares multiple treatments with a control treatment.
Kind regards, Garry
