Solving heterogeneous variance using mixed linear models

Folks,

I'd like to set up a mixed linear model with one factor and one linear
covariate. No random factors or repeated measures, but residual
variance is to be estimated separately for each level of the factor.

I've fiddled with the Mixed point & click interface for a while trying
to fite this model, with no success.

Any pointers would be appreciated. I'm using V20 for Windows.
