Updating Models and Assemblies

Need to know if after updating a part models geometry can Istop it from updating the model anywhere else it is used. Forexample I change the OAL of a component and I go to open theassembly that its in can I have the option not to update the modelsgeometry yet and manually change it when I need to. The issue iswhen someone makes a change they don't update all the where usedspots ( assemblies ) and no down the line when I open them up theyhave dimensional changes with no revision and the drawingconstantly stays on the same rev level even when it changes.
Can anyone help me with this issue?SolidworksParts And Features
