Change default action of "Add To Job Queue" button?

When I’m re-reshuffling lots of files, I add them to the queue, of course. My problem (heh) is that I have to go through the tremendous effort of clicking on the drop-down box to select “Afterwards create new multiplex settings and close the current ones”.

Now, this functionality may already exist and I just missed it, but if not, it’d be cool to have an option in the Preference files to choose which function they get by just clicking the button. [I would put a smiley face here, but it turns into emojii]

Either way, thanks much for this, I know my way around ffmpeg, to some degree, but MKVToolNix is just so much easier!

Preferences → Multiplexer → Clearing settings automatically

Ha! I figured that was already present, and I just didn’t see it. Thanks much!
