st: Meta-analysis, Breslow-Day test for non-binary variable

Dear all.
Using -mhodds x y, by(z)- I have analyzed the relation between -x- (0 or 1) and -y- (0 or 1 or 2) in two cohorts (-z-) to get pooled OR and M-H for homogeneity.
In a review process I am now asked to provide a P for homogeneity by Breslow-Day instead of Mantel-Haenszel testing. Does anyone know if and how this could be calculated by STATA?
As -y- is not binary -cc x y, by(z) bd- will not work.
I have tried to use -meta-, -metan- or -metacum- but a Breslow-Day test seem to be possible only if -y- is binary.
Many thanks in advance,
Berthold
