That's not really the way that the Congressional mail system works.
Also, it's much more impressive to have a barrage of letters to each congressman, rather than a bulk folder that contains all the letters to that congressman.

But maybe they don't have a centralized mail room? I didn't actually check.
The people working in the congressman's office are the ones who actually have the working relationships with the elected officials (to the point where they can sometimes pressure them if they think that constituents are feeling a certain way, based on calls/letters).
