Simon,
there's actually the possibility to define a quite close "definition query":
Layer Properties --> Simbology tab --> Categories tree --> Expressions
option --> click on New expression of filter --> ...and so on
The only missing feature is that the filter is not applied to the table
of attributes. Hope this helps!

Cheers,
Antonio
