Fusion Cloud Cash Management - Multi currency bank account

Summary:

Hi,

Can we achieve the following cases, as the current understanding is multi currency bank account works as long as bank account currency is same as Ledger Currency.

However, would like to explore the capability to handle transactions in multiple currencies 

Case 1:

Bank Account: USD

Ledger: USD

Invoice and payment: EURO

Case 2:

Bank Account: SGD

Ledger: USD

Invoice: SGD

Case 3:

Bank Account: SGD

Ledger: USD

Invoice: EURO

Case 4:

Bank SGD

Ledger: USD

Invoice: USD

Thanks,

Saurabh.
