Is it possible to delete some of the changes returned by 'sp_fulltext_pendingchanges'?

I'm referring also to this post: http://social.msdn.microsoft.com/Forums/eu/sqldatabaseengine/thread/67d77c7e-a3e6-48bc-a851-614d261e3a5e

I've kind of a unique situation, I've my full text index with manual tracking and I need to delete some of the tracked changes before updating the index.

With this query I can see all the tracked changes:

DECLARE @table_id int = OBJECT_ID('MyTable');
EXEC sp_fulltext_pendingchanges @table_id;
GO

How can I delete some of them before updating the full text index?

Thanks a lot!
