How to get less than 4 journal files per a journal in qpid broker?

Issue

We are using durable queues in qpid broker just for persistent provisioning, i.e. we don't send there a durable message.

However, creating a durable queue implies journal with at least 4 files to be created as well.

As we don't utilize the journal at all, is it possible to prevent creating it? Or at least to create less files in order to save system resources (disk space, open file descriptors)?
