Thank you for the suggestion. However you could publish the document and link it. If for example you have a document list somewhere else in the site where all the documents are available you could filter the list to not display the undesired document and I believe this way you can achieve your scenario.
For example you have category1 set for all documents except the one (which is also published) that you do not want to be visible in the Document list widget. You are therefore filtering the widget to show documents of with category1. You can open the document and add category1 to it, but you schedule it for publishing with the page.
This way you can safely work on your page and link to the document, then schedule it (the page) for publish. In the mean time the document will not be visible anywhere else. Upon publishing time the process will be fully automated and you will not have to go edit the page nor the document - they will both appear properly.
All the best,
the Telerik team
