Option to create duplicate window / tab inside tabular editor window manager

- i want to be able to make a small change to a pivot grid without losing my current pivot grid. currently i have to create a new tab/window for the pivot grid and then rebuild the entire pivot grid manually which is very time consuming - i want to add a new dax query with a few changes from my current dax query. i currently have to copy all, create new query, then paste all right clicking on a tab should offer a DUPLICATE option which creates a new window with the same content again in it - -
