*ADD_DIM concatenate two properties for defining destination member

Hi all, I would like to know if it's possible to concatenate two properties from two dimensions for assigning the destination member in Destination app for script logics. Here' my case:

Source app: Planning model (Has ACCOUNT and COST_CENTER)

ACCOUNT.ID = 100000

COST_CENTER = 200000

Destination app: Consolidation model (Does not have COST_CENTER, only ACCOUNT)

COST_CENTER_MAP = 100000200000

So far I have tried:

*SKIP DIM = COST_CENTER
*ADD_DIM COST_CENTERMAP = ACCOUNT:ID%%COST_CENTER.ID

*SKIP DIM = COST_CENTER
*ADD_DIM COST_CENTER_MAP = ACCOUNT:ID COST_CENTER.ID

*SKIP DIM = COST_CENTER
*ADD_DIM COST_CENTER_MAP = ACCOUNT:ID+COST_CENTER.ID

Any thoughts? Thanks
