Nerworker Clone to LTO - parallelism in action

I would like to make a clone backup of MSSQL databases to LTO tapes.
I have a library with 6 drives.
Let's assume I have 60 savesets of 1GB each
Can I set parallelism to 6 in the clone action definition and save the clone in 6 times less time to 6 LTO tapes?

@tom1973a , Tapes are sequential media and supports multiplexing only on write and not on read.
You could grab savesets from different tapes and then run parallel clone jobs and your plan here could would work but incase all the source savesets are in a single tape then no, this will not work.

We've had this problem too, but haven't found a way around it yet other than running nsrclone as a script.
