Word side bar plug in to insert Content Controls into Word documents

The request I have is, would you be able to do a side panel to allow users to easily assign Content Controls to pieces of text within their documents and turn them from docx contracts to template ones (still DOCX - I'm not sure we need actual word templates unless there are specific good reasons I don't know about .) I would provide the side bar code initially and this would contain a windows form. What I want the users experience to be: * User opens document and clicks a button to have the Template Design sidebar appear (I could provide this bit) * If a JSON file with the same name as the document exists then it will populate a drop down in the sidebar. **This JSON file will have the names of the properties which would come from the Survey prior to downloading the document. * The user would select some text within the document and click a button in the sidebar. * If they had a property selected then they would have the property name filled out from that name * ELSE they would be able to either: ** Take a suggested name which would be calculated from the context of the area selected ** Input their own name ** A suggested name would be calculated from: *** A title immediately proceeding the paragraph which was highlighted *** A sentence immediately prior to the text highlighted *** The text selected * In all cases the suggested name would be: ** Text lower cased ** Spaces would be converted to _undercores_ *** E.g. loan_amount , counterparty_name * Default Text would be a multi-line control which contains the text selected and allows the user to change it to be more in line with the change from a working document to a template. * I think it makes sense to allow the user to choose a colour for the content control * I'm not sure which of the other aspects of content controls need to be settable through the form, e.g. Tags * Once set, the user clicks a button and the document is updated with the Content Control * If the user clicks on an existing Content Control then all the aspects of that content control should appear available to edit * If it is easy to be able to find all instances of the same text and have them replaced within the document with the control then to provide a button to achieve this seems like a sensible request. Some additional pieces: (which you can price separately) Provide code to demonstrate how to replace update these content controls with custom text through the CustomXMLPart being updated. A method to strip out the Content Controls - effectively "harden" the text within the document so that the CustomXMLPart cannot be used to update it further.
