We are trying to create a record series folder under record series folder using Java code but unfortunately we are not able to create that folder

While creating a folder in Java we are  using the below code in which we are not able to give the option (EntryType as Record Series) to select the folder as record series folder

//Folder newFolder = Folder.create(rootFolder, EntryType.RECORD_SERIES , session);            

above is the code which we are trying to achieve

We are able to achieve the below code but this is not we are looking out
//Folder   newFolder = Folder.create(rootFolder, EnumSet.of(EntryNameOption.NONE), session);

Please let us know how we can achieve this in java or let us know is there anyway to create record series folder through java.

Thank You
