If I set the crafting combinator to craft an item that I don't have the research to craft, then it will give the assembler no recipe, and it won't switch the signal to craft any other items. Is there a way to filter a set of signals for the recipes that have been researched?

I would like to use a constant combinator and the crafting combinator to configure a machine to craft a small amount of several different items, some of which I may not have researched yet. I would also like to share the blueprint with others (who might not have researched everything yet). The problem I keep running into is that the crafting combinator "selects" an item that can't be crafted yet and then the assembler gets stuck with no recipe. And nothing is ever crafted.
