Speed up multichannel time-stretching (one ZTX instance per channel)

Currently (v14.0.4) the time stretching using ZTX utilises only one processor core, even when processing multichannel audio. Judging by https://zynaptiq.com/ztx it seems that if an API call was made separately for each channel, a speed up of [the smallest out of processor cores and audio channels] could be achieved.
My use case is changing the speed of a 5 minute take of 58-channel multitrack in a classical edit, on a computer with a 12-core Intel Xeon W-3235
Many thanks,
