The MailMerge.Datasource for my MS-Word mailmerge is an Excel-Table,
and the first column in that table contains a group indicator. Rarely
all addresses in the table are to be processed, but they are to be
selected according to the group indicator, excluded or included.

Unfortunately the dialogs both of MS-Word as well as Excel do not
provide enough options to present all the group indicators.

So I would like to build a MS-Userform with a dynamically built
table of RadioButtons for each group indicator found in the Excel
table, but I am not sure how to approach a solution for that problem.
In pure SQL, I would submit a SELECT UNIQUE column_1 FROM the
MailMerge.Datasource, but I don't know if this can be done without
confusing MS-Word's Mailmerge process, and also I don't know if Excel
does not have some home-brew methods to achieve the same result, for
which I would call the Excel-Application to do the work for my MS-Word
VBA program.

Any hints on where to go from all thos most valued experts?

L.W.
