changing generated domain model entities from Non Persist-able to Persistable

I have to ref a massive web service model and generate all my entities from it. Is there a way to generate them from the start as Persistable yes, Currently default is No. Also is there a way to change all entities on a domain model persistable state at once besides going through them one by one. Thanks

AFAIK there is no fast option to do this, they need to be changed manually one-by-one
