Yes, but you don't need to set gnus-registry-marks.  These are the
default marks.  Set it if you want to override the characters shown
(e.g. greek tau for To-Do).

You need this:

(defalias 'gnus-user-format-function-M
          'gnus-registry-user-format-function-M)

And then use %uM in your summary line format.

If you or anyone else has the time to write this up in the EmacsWiki,
it would save time for the next person to need it.  I'll write a
manual section on this when I have a chance, but the Wiki seems quite
popular these days.
