Dimension Build with Shared Members

I need to build a dimension using Parent/Child references from a load file that is not in any particular order. This would ordinarily be no problem since I can allow moves when I load the dimension, but there need to be shared members in the dimension. When the load encounters a shared member, it moves the initial member rather than creating a duplicate member.

I have tried loading the dimension in two passes, first allowing moves, then without moves, and this almost works... but it makes the first occurance of a member shared, and the last occurance a stored member rather than the other way around.

If I have to I can manually edit the outine to fix this, but it seems that there must be a better way. Any suggestions will be appreciated.
