R12.1.3 Link OU to LE

Hello,

Is there is a way to link specific OU to specific LE which share the same Ledger in R12.1.3?

Example, for the following Org Structure:

Business Group1

LE1, LE2, LE3,

Ledger1

OU1, OU2, OU3

We know how to link LE1, LE2 and LE3 to Ledger 1 (GL Accounting setup).

We know how to link OU1, OU2, OU3 to the Ledger 1 ( Organization setup)

Is there a way to link OU1 to LE1, OU2 to LE2, and OU3 to LE3?

Thanks.
