Preserving annotations across merges?

[Chris Johnson \(chjohns2\)]

Is it possible to preserve annotations when you merge branches?
 
For example, I have two branches A and B. B has bug fixes made to it and
A has new features. We want to merge B to A, but I'd like to have the
annotation history merged also. Currently when we do the merge the
person doing the merge that commits the changes into A, is shown and the
modifier for all the changes in the annotations for branch A.
 
I don't think this is possible, but I thought I'd ask just to make sure.
