JDE Allocations Subledger C to Cost Centre

Is there any way to allocate amounts which sit on a single business unit split by subledger, where the subleder represents business units to the individual business units without having to set up all the lines one by one for each subledger and business unit combination?   How can one indicate that the subledger on the original business unit should be used as the business unit for allocation purposes?

Eg

BU 100.4110 s/l 1000 $60

BU 100.4110 s/l 2000 $90

BU 100.4110 s/l 3000 $120

say 1/3 of these amounts are to be allocated as follows:

1000.6110 $20

2000.6110 $30

3000.6110 $120

Thanks
