Thanks for the ability to set modules per recipe! I'd love to also have the option to be a little more general. I'd like to put productivity modules in assemblers if I can and then fall back to speed if it's a finished product for example. I'm not consistently inserting with the same recipes, so it would be a big help to be able to split by intermediate and finished, to have the default modules row act as a fall back, or to try rows with assemblers in sequence in case the first row doesn't work. Thanks!

You can do that, or at least something functionally similar. You can add extra "fallback" module sets to any row to do what you described - if the first set has productivity modules and the current recipe/machine doesn't take them, it will try the next set. In the sample image, the default module row is configured like that - it will place productivity modules in anything that accepts them, if not then it will try quality modules, and if those also don't work it will try speed modules.

Or are you thinking of a situation this doesn't cover?

Oh cool! I didn't realize you could add another row like that. That's perfect. Thanks!
