Inter and intra cash pooling how to handle in Oracle Cash management and treasury

 Hi Folks,

We have 4 bank accounts ex: A,B,C,D accounts A & B will come under Legal entity 1( LE-1), C& D will come under Legal entity-2 (LE-2).

Now we have defined Cash pool for intra in Legal entity1 between A bank account to B bank account?

again can we select A bank account and C bank account for pooling  in Treasury module ?
