Payment subaccount

hi good morning chiefs
i have some questions:

  1. when making transfers from the subaccount will the name used to create the sub-account be the one that will reflect when transferring out of the subaccount to other banks?
  2. is there any clause involved because I noticed the requirement is not as tight as a virtual account that needs bvn for it to be created.?
  3. Can one transfer in from and out to any bank?
