add second property to translatable() directive

[lex10000]

Hello!

Is it available to add second property $fieldValue (null by default) to translatable directive?
Try to explain. I develop EAV (dynamic) NOVA package, and i want to use translatable power of you package. I want to filll values of fields by using fillCallback(as third attribute in my field), but with this attitude i cant do that, because your directive try to find value in current resource. It would be very nice if you do that, cos other users could pass to this field any value as they want.

Attach a screenshot with my solution.
Thanks!
