Not really basic, but can be done.  The problem is that
the slice at the level is still a 3D grid and the topography
is a 2D grid (hence the "domain dimensions must match" error). 

You can get around this by using the formula Grids->Make slice 2D
as a wrapper around SST.

Select the formula
Select Contours over Topography
When the topography selector comes up do your Any Field dance
When the slice selector comes up, choose the SST and the level.

I actually had code that should do this automagically, but see it
only works when the topography doesn't have a time dimension.  I'll
fix that for the next release.
