When a cell is selected to be placed as a label, it is transformed to a new label element type. Therefore the Replace Cells function cannot be used after the cell was changed to update all labels in a model. Currently all placed labels need to be deleted and the new version be placed.

As a user I'd like to be able to update a label from the cell library (single mode & global mode) rather than deleting and replacing all single labels manually and keep the association to the graphical element
