I have a convoluted way of doing it.

First, I define a topic index and a parallel topic seeindex which 
gobbles the page number:

    \defineregister[Tindex]
    \setupregister [Tindex][n=2,
                             command={\Word},
                             balance=no,
                             method=default, % or New follows Newton!
                             compress=yes,
                             check=no,% allows seeindex to plussed entries
                             expansion=yes,
                             pagecommand=\IndexPageCommand,
                           ]
    \defineregister[SeeTindex]% see also index for Topics
    \setupregister [SeeTindex][n=2,
                                command=,
                                balance=no,
                                method=default, % or New follows Newton!
                                compress=,
                                maxwidth=2.3in,
                                expansion=yes,
                                pagecommand=\gobbleoneargument,
                              ]

Then I can index normally

         \TIndex{quotation+direct}%
         \TIndex{quotation+indirect}%
         \TIndex{marking}%

except for the see also entry, which requires:

      \setregisterentry[SeeTindex][keys:2=zzz,entries:1=punctuation,entries:2={{\em
    See also} marking}]%

and then I can get
