Enable Excel-JS to open a workbook in the same document as the addin.
Excel-js currently have new functionality to open up a new workbook using "Excel.createWorkbook", this opens up a new document with the workbook. I would like to suggest functionality where the workbook is not open in a new document, but instead in the same document as the add-in.

Couldn't agree more. One of the biggest drawbacks with createDocument, createWorkbook, and createPresentation is that it opens in a new window and the add-in (and add-in state) is entirely lost. Could this be implemented?
