Copy a whole page including formatting from one PBIX to another.
To be able to right click on a report page within a PBIX and select 'copy' and then enter a different PBIX and then paste that report page. Similar to what you are currently able to do in Excel. Ideally all the settings / formatting would also be copied from PBIX to PBIX.
Though it great that your able to copy a visual from PBIX to PBIX it needs to go a step further. This would save a lot of report developing time and could be used in a number of ways.
I've been caught by this several times, especially when picking others' work, edited between Report Server and Service versions od PBI Desktop. It'd be very useful
As a side note that may help someone reading this. I've found the selection pane to be very helpful to select all visuals on a page very quickly to be able to copy and paste the whole page.
Seems this should be one feature of an overall capability around moving/migrating workspaces and their contents.
