document template for new ebooks

==========
I am able to 'eASILY' add the following document propertires in the main document text portion of the DOTX file... and these field seasily pass into Calibre:
-Word Document Standardized Property "Title" = Calibre Field "Title"
-Word Document Standardized Property "Author" = Calibre Field "Author"
-Word Document Standardized Property "Company" = Calibre Field "Publisher"

('eASILY' = I can pick the Word Document property and make it a grey highlighted text input field in the document text portion of the DOTX document)
==========

==========
I am able to 'nOT-eASILY' get the following tag fields into word document properties.... in an approach that is conducive to import into Calibre
-Word Document Standardized Property "Tags" = Calibre Field "Tags"
-Word Document Standardized Property "Comments" = Calibre Field "Description"


('nOT-eASILY' = I cannot pick the Word Document property and make it a grey highlighted text input field in the document text portion of the DOTX document... it is inconvenient to have to click "file" and edit properties there.)

Is there anyway to create a DOTX template to'eASILY' (^above^) type in the following word document standardized property fields so the DOCX import process also passes the following fields into calibre?
-Word Document Standardized Property "Tags" = Calibre Field "Tags"
-Word Document Standardized Property "Comments" = Calibre Field "Description"


Does Calibre support "Custom" DOCX property fields?
-Word Document Custom Property "CalibreFieldSeries" = Calibre Field "Series"
-Word Document Custom Property "CalibreFieldSeriesIndex" = Calibre Field "Series_Index"
-Word Document Custom Property "CalibreFieldID" = Calibre Field "ID" (for me all ID's are "url:https://path.to.source/destination.html")
-Word Document Custom Property "CalibreFieldGenre" = Calibre Field "Genre"
