Is it possible using Office 2013/SharePoint and SharePoint Designer to create a confirmation on delete pop up.  I have a workflow that kicks off when a button in the menu is selected that deletes the currently highlighted document.  We would like to have a confirmation pop up form asking "do you really want to delete this or were you just @#$% around again". I wish, no it should say something like "Select Yes to delete this document"

Now there is a very good blog on how to do this in SharePoint 2010... http://blogs.sharepoint911.com/blogs/jennifer/Lists/Posts/Post.aspx?ID=50

But unfortunately step Five customizing the form cannot be done in 2013 document libraries, or I do not know how to

There must be a way to do this in 2013, any help doing so would be greatly appreciated.  Thank you.
