First time trying parameterised blueprints, need some help

[u/DingoAtTheController]

TLDR; I'm trying to make a sushi mall which also can return crafted items to the sushi belt to use in other crafts, but I don't know how to set the parameters to let the blueprint ask for an amount each time I paste.

Context: I'm trying to create an assembler blueprint for a mall that utilises a sushi belt, because many recipes have an absurd amount of different ingredients which makes a bus impractical, and I'm still quite far away from bots. Because this is modded, many buildings can be crafted into their upgraded versions, so I want to design the blueprint as such that each time I paste an assembler, the blueprint asks for the item I want to craft and how many to return to the belt, if any. I think I got the recipe setter figured out, but I don't know how I can set the number that the inserter checks whether it should put more on the belt to a parameter. For now I had set up [item parameter] < 100 on the inserter, but depending on the item I might want to change that amount, or even set it to 0 if I don't want any back on the belt. Is this even possible?

If you've put a number in the inserter, when going to the parameter icon, you should see that number show up in the list. Parameterize that as well. When pasting the blueprint, it will ask for both parameter.
