Number of Directories required for Payment Disbursement Ackowledgement

Hello

Greetings!

We have 6 payment batch runs per day and for retrieving Disbursement acknowledgement for them do we need to configure 6 different payment directories if we are using SFTP Client as we Bank server allow only one connection for every 15 mins

Also if we consider to implement 3 level disbursement acknowledgement then do we need 3 directories to store each of the level file

Thanks
