Can we change the Group location of a Function object ?

Hello all, hope anyone can help here :-) 

In the current Data Base, I realised that there are function objects with incorrect Group Location (Properties > Information > Location) that information is grey out so seems that cannot be modified (as also includes the GUID) - but is there a way to change the Location of an Object ? In this case a Function object within a Process Value Chain Diagram Model ? 

Thanks!
