Presets for audio and subtitle passthrough

[raadhey]

I'm using the docker container on Ubuntu server OS installed on an Intel i5-7500T machine. I am trying to automate the conversion via the /watch directory.
I was able to create a preset from the webgui to select H265 encode.
I would also like to ensure audio passthrough and (if possible) subtitle passthrough.
Manually I can set it the passthrough for a file/ conversion job, but when I try to save it as a preset I see that it has no effect.

So my Question is whether it is actually possible to set audio and subtitle passthrough as a preset?
My intention is to convert to H265 to reduce file size and keep CPU utilization low (QSV for the video encoding) by not doing audio decode-encode.

Please let me know if I have missed these steps from previous discussions. I have tried to search extensively and also looked through reddit and other general searching around.

Thanks.

Under Audio and Subtitles tabs, at the left you can select "Track Selection". This is where the magic happens.
For Audio, see #222 (comment).
For Subtitles, this might help: https://www.reddit.com/r/handbrake/comments/nlm4gl/passthrough_all_subtitles_in_mkv/
