The current implemenation already has this.

I believe all this can be addressed by implementing specifice
load/save_override functions in an archive for specific datatypes and/or
templates. I am currently improving the implementation to make it easier
to derive one's own custom archive from one of the provided ones.
Presumably such this would be used to provide special/different
handling for situations as you describe above. The next upload
draft will include these improvements along with a case study
showing how to handle cases such as the above.

Unfortunately, using this facility will require a careful review
of most of the manual.

BTW - currently it would be easy to make a custom version
of binary_i/oarchive which is the simplest of the lot.
