Is there a way to do the above? If so how?

Short answer: no.

Longer answer: It's been requested multiple times and is being considered for a future release.

There are ways to configure yourself around these limitations by configuring more storage units and reducing the maximum size of a destage run to force it to kick off more jobs. Then you'll run into issues on saturating your disk subsystem... With an LTO-4 taking up to 400MB/sec of well-compressable data, how many of those streams can your disks take?
