I have an excel workbook that I would like to share with multiple people so they can simultaneously edit the workbook, but not see each other's edits. I need this to be in Power Bi so the users have the reload option which will clear whatever data they entered to the workbook. And I would like to be able to share this workbook via a linked button in another power Bi dashboard. The option "Pin to existing dashboard" is grayed out and I am unable to select it. Any recomendations?
