load rule to move shared members

Hi

I have two load rules.  The first loads a stored member to the main hierarchy; and then the second loads the same member to an alternate hierarchy (ASO).

If I 'allow moves' on the secondary load, the job simply moves the base member to the secondary hierarchy.   What I would rather is that it creates a shared member if it doesn't already exist. Or, if it does already exist update its parent member if that has changed since last load.

Can anyone offer a way to allow the move of the shared member without impacting the base member?

Cheers
