I have a situation where I am extracting several entities from a single user utterance. I need to ask a followup question for each entity. Is there a simple way to implement this? I tried creating a loop in the dialog graph but that quickly became fairly convoluted.

Please refer to Named Entity Recognition. It could be what you are looking for.
Individual prompts will be there in entities. If anything is missed, it will ask for it. Otherwise it should pick form the utterance.
You may need to ensure for the entity to allow unused text from utterance for entity value.
Hope this helps.
