Forms: Add another person to edit or see

Yes. Two examples:
To edit: we are a group of teachers who teach the same students in PE. We would like to make a quiz at the end of an activity to see if the students understand. But as we are more teachers it would be nice to all be able to add questions and read through and edit the questions already made. Therefore it would be good with rights to edit in the organization. It could also be the students who wants to make a questionnaire to their classmates but they are more people in a group and sitting at home and want to edit together just like you can do in the other online/browser apps like word, PowerPoint excel ect.
Second example is to be able to show the results to another person: eg I made a questionnaire about how many students were able to go on a science trip but since we are two teachers and other teacher asked how many were going and what their answers were I had to save it as an excel fine first and then send it in outlook to my colleague. It would be easier to be able to say : share result with "email" or person in organization. I also know that Google analyse has the posibility to show results after a person took the questionnaire. Not sure this is nessicary but idea is pretty good in some circumstances. :)
Further more I asked a question to whether it was possible to give a certain amount of answers but which could only be chosen once where as they would get hidden or untouchable for the next person to chose. Eg. When we plan our parent-teacher conferences we have maybe twelve time slots in a day two days in a row and to make it as fair as possible we let the parents chose their day and time. And ofcourse first one first but this way it seems like everyone get something durable. But this would have to be so that when one time slot has been chosen no one else could then chose it and only the available once were left to chose. This would be great. If a solution like this as well as another two or three changes to other programs could be made, then soon our school could almost be office 365 only :)
Fingers crossed
Hope it's understandable, if not please don't hesitate to write again :)
