MS Team for education - MS Surveys as assignment

Hello guys

So far we can attach a MS  quiz as assignment in a classroom . But we cannot attach a survey.
What we want is to get student self evaluation about their competencies OR just gathering some feedbacks.
Having this as assignment is nice : it can be scheduled, evaluated etc..
Do you know if it s on the backlog..... and if we have any workaround? 

thx !
