Hi Ray thanks for posting! We don't have a specific watermark feature but you could definitely create your own watermark from an image or shape by placing it in the corner of your diagram making it transparent and locking the shape/image to ensure that the size position and formatting stays consistent.  If you have multiple pages in your document you could create a Master Page so that all subsequent pages would have the watermark in the same place. For more information I recommend taking a look at our Modify Format and Style Shapes and Master Pages articles from the Lucid Help Center. Hope this helps!

Lucid Support:
It would be helpful if we could insert the document status, as a variable value, similar to how you allow documentName and pageName to be inserted in a text box

These links do not work..

Hi ​@daph, sorry about that! It looks like those links were from a few years ago. We have since updated this Help Center content. I now recommend taking a look at the article Create a master page in Lucidchart, and now also recommend the Upload an image portion of the Add and customize shapes in Lucidchart article. Please don’t hesitate to let me know if you have any additional questions or concerns!
