Wondering if there was was way, other than conditional fields, to use the same drop down list multiple times in the same form?

For example, this is a supply list that has a 40 item dropdown menu that needs to have a quantity applied to each item selected in the drop down field. Currently, I'm using a conditional field that when the user is done making selection and selects "no", the submit button appears and the form gets submitted.

I'd like to know if the user selects "yes" to make another selection, that the next drop down list & quantity field (identical to the first one) appear but I'd like this to happen dynamically, if possible.

I know I can make these fields & duplicate them within the form field section in the backend but that is tedious. Plus, if a change needs made to the list, I have to make the change for each instance of the drop down field and in this case there would be atleast 40 duplicates that would require a change using the same dropdown menu.

Would like to hear if anyone has any ideas how to accomplish this or can show a working example of a RSform using multiple drop down items & quantities that accomplishes this, either how I explained it or in another fashion.

Looking forward to replies!

Did you figure out a way to do this? I have the same problem.
