Pausing a tethered shoot in Darktable

I use Darktable to document my oil painting process with a tethered shoot. But often I need or want to pause the shoot, so that I can prepare further colours or simply take a break.

So far I have not found any option to pause or resume the shoot. These leads me to having to kill / quit Darktable.

If this feature does not exist, could it please be added to Darktable?
