I did entry quantity steps to 1000 but on-site front end when we add the product it increases by 01 unit only? Any suggestions on how to overcome this?

Did anyone solve the above question? We cannot get the quantity steps to work either...

how can add this function to a specific product?

Is there a way for it to exclude certain products or only applied to certain categories?

Did anyone find the answer for Ibeetles question? I am also looking for than answer
