We should be able to right click on a view and have the option to replace that model reference in this active sheet, not in the whole document, the only way i have to do this from now is delete and restart the sheet, or enhaced the replace model reference window to let us know wich sheets we are replacing the model and maybe add some option in the window something like search or filter or at least the option to enlarge the window to see the full name of our .ipn/ipt
thanks you !!
