Cross Ledger Allocations?

We have a requirement to be able to do a massallocation from one cost pool account in one ledger ($100 in Ledger A, for eg), to different target/ offset accounts in other ledgers (Ledger B for eg).

Is there a way to do this so that the balance of the cost pool account gets completely offset by the allocation entries made to ledger B(meaning, after the cross ledger allocation the balance of that cost pool account in ledger A is $0)?

R12 has a restriction that the Target and Offset accounts on the formula lines must belong to the same ledger.
