File split / recombine to increase VEIA throughput?

I use VEIA daily to upscale original content for streaming at 720P. Artemis MQ with .5 grain works well for 720x480P sources. Using a 24-core AMD 3960x with RTX2080i GPU, upscaling averages 2.5x real time. (1 hr content takes 2.5 hours.)

If I split the hour of content into three 20 minute videos, and run three instances of VEIA, the hour of video is done in 56 minutes, since one instance uses slightly less than a third of available processing power. Running three instances, the PC becomes a handy space heater, an added benefit in cold weather.

Any chance of offering a file Split/Recombine option for machines with extra cores available? (I can do it manually with an editor, but automation would be super useful.)

Or maybe this upgrade opportunity has been addressed, and I missed the post?

Regardless, thanks for fielding requests like this.
