Annotating Ref Des in schematic yet not impacting Layout parts

Does anyone have a way to change a Ref Des for a part in Capture and not have it impact the part in Layout?

Typically when a Ref Des is changed the part is removed from the layout but we'd like to keep the circuit intact and just rename it following our page numbering sequencing.

Sheet 1 = 100 to 199, Sheet 2 = 200 to 299 etc.

Any comments would be helpful.

Thanks
