Parallel upload via UI

Is it possible to have kopia upload in parallel when using KopiaUI? (equivalent to kopia snapshot create --parallel 24 option).

Perhaps it can be configured in the policy?

Context – upload to B2 datacenter (Both US and EU) from EU seems to cap at 100kbps… with speed test to DE and CA,US I’m getting over 30Mbps, so it is something with the B2).
