separate GL batch to be generated for payable invoices

 Client has a requirement to post the sub ledger entries in GL by journal wise. 

I had changed the sub-ledger accounting option for payables: "General Ledger Journal Entry Summarization to No Summarization".

Scenario: -Entered two invoices in AP and done Create Accounting "Final"
- Ran "Transfer Journal Entries To GL"
-In GL requried the journals and selected one invoice journal and click on "Post" button
- but, automatically second invoice journal also selected for posting

user don't want to post the other journal without clicking on post button.

In this scenario, we might need to customize SLA in order to generate separate journal batch for each & every AP invoice.
