I assume you mean that you would like some actual text in the Summary
buffer to have the string "1" or "2".

There are only three things that you have to do for this:

1. Make sure that the X-yzzy field is being put in .overview.  If it's
   not by default, then add it to `nnmail-extra-headers'.

2. Create a new function `gnus-user-format-function-y' that looks at
   the X-yzzy header, and outputs "1" or "2".

3. Add %uz to wherever in `gnus-summary-line-format' you want it.

I guess you could do something in the `gnus-article-prepare-hook'.

Of course, you could also mess with the message itself somewhere in
the processing before it gets into Gnus in the first place.
