Ability to Change the Tab/Page Order for Relationship Diagrams in the Model View

Currently there is no way to shuffle or move the page names in a relationship diagram in model view. So, if I have a "FACTSales" and then "FACTGrossProfit" and I want the pages to be ordered alphabetically, there is no way for me to click and drag and reorder the page names so that FACTGrossProfit appears alphabetically BEFORE FACTSales. I am stuck with the order in which the model pages were created. Report pages are easily rearranged. Model View Pages need to be the same.
