Removing text from table, not for all occurences of table

How can I remove parts of an Aspose.Words.Document that is in a table for a specific occurrence of the table.
If the text is in a bookmark and the code removes the bookmark, the bookmark will be removed throughout the table and not just for one occurence/instance.

Is there a way to specify to remove the bookmark in a specific occurence?
Is there another approach for removing parts of the document in a table – not for every occurrence, but specifically for one occurrence?

Thank you
