Multiple entities for same slot

Rasa Open Source

So Im trying to process multiple entity extractions for a slot. I have 3 entities: Company, Product and Quantity, all 3 of text type.

For ex.
I want 1 Dominos pizza

Output dictionary={
quantity = 1
product = Pizza
company = Dominos}

So when i run this, they each get extracted individually , cause I have used RegexEntityExtractor and 3 Lookup tables for mapping the 3 entities. I have also used the utter_ask_company and utter_ask_quantity which works for making sure values are filled. Problem arises when I have multiple entities for same slot. Ex. I want 1 Pizza and 1 Burger

Output dictionary={
quantity = [1,1]
product = [Pizza,Burger]
company = None}

Which Company? Dominos

Output dictionary={
quantity = [1,1]
product = [Pizza,Burger]
company = Dominos}

I want this to ask me “Which company” twice(for burger and pizza), but it asks me so only once which makes sense, but I have no idea how to fix it.

So i want it to ask me which company and quantity for unfilled slots for the number of products that I have. Any Input would be appreciated.

How about entities role

So I had seen this, but it said I could only use it with DIET and CRF, but I had used RegexEntityExtractor so I assumed it wouldnt work with it.
