add possibility to add default label for core:NotInstantiatedClass feature, e.g. isRemoteClass

[SteinerPascal]

 ?Tree_4 <http://twin-example/zurich#agrovocBroader> <http://aims.fao.org/aos/agrovoc/c_6409>.

The objectproperty is subclassed with core:NotInstantiatedClass That means no endclassptrn is created but i would still like to have the defaultlabel ptrn created like this

 ?Tree_4 <http://twin-example/zurich#agrovocBroader> <http://aims.fao.org/aos/agrovoc/c_6409>.
<http://aims.fao.org/aos/agrovoc/c_6409> skos:prefLabel ?someLabelVarName

Is there a workaround for this? What kind of varname would be chosen?
