Pass MappingLabels across Generators

Hi,

is there a way to pass MappingLabels across different Generators?

We have a project where we need to generate a bottom layer of different Java Classes which need to be refered from another layer of classes. Those layers are beeing generated by different generators and because of that, we arent able to refer the first generated classes by the second ones.

What we need is a way to refer those generated classes in the following generators.   

Is there a possiblity to share or persist those mappingLabels?

Thanks for any help,
Simon
