Unfortunately not.

I've opened a placeholder bug report for it so it won't be forgotten:

https://savannah.nongnu.org/bugs/?44644

I once started an implementation attempt for it (I'd need it myself at 
work as well), but stumbled across some roadblocks.  In particular, 
writing the signature rows must be done pagewise, which would 
require yet another page cache.  That, in turn, is asking for 
implementing generic page caches, rather than adding a third hack ...

But well, maybe it's simpler to just add the hack, i.e. some more 
stuff to add to the private programmer data block in each programmer 
implementation.
