Multithreaded psd / psb file save compression

Hello everyone!
I am a retoucher and to speed up things I do my work disabling file compression while saving.
When the job is done and approved, I made an action to just open the file select a group of layers and then it saves the file.

Quite happy about the result in terms of time wasted while working, which is almost done, but this way I make the life of my NVME shorter and I lose a lot of time running the final action and archiving the files.

I know PS can save in background while we work but we cannot create smart object till the saving process is ended. So almost every image I am stuck for 2 minutes.
I have 5950x and it is a shame I cannot use the full potential of my CPU, but even the cheap cpus have 8 threads now.

Please let me know what you think about it
Thank you
