Hi,
No, this is not an option yet in Workfront.
Alternatively, I would suggest having all basic general questions in one custom form.
And for all specific assignments have a specific queue/custom form set. When you are adding these under project queue topics, make sure to add the general custom form and the respective custom form to those queue topics and default assignees before you save. This way we are letting requestors choose the right queue before they add details. (Enclosing screencapture)
Second alternative, is to use fusion. I understand this is possible with fusion.
