Changing signatures while using "set reverse_name"

[Lance Simmons]

I use "set reverse_name" to change my "from" header.

I'd like to be able to change my signature depending on what my "from"
header is. Is there a way to this?

If not, is there a way to get the same effect as "set reverse_name" while
still being able to tie the signature to what address I'm using?
