Can we use Sub-Ledger Accounting method across two COA

We Have a requirement to create a New COA and Ledger/OU for a different Country, we are using one custom SLA Method (user ) in our existing OU which we would like to use for the new entity as well,

The Tranasction and Accounting Flexifeild were assigned to the OLD COA under the OLD SLA Method.,

For the new Ledger - we would like to reatin the same COA structure however the values would be different.,

Given This, Could you please suggest if we can reuse the existing SLA Method to create a new Ledger, Pls advise
