Features we need. Are these available.

Hi, I'm new here so hopefully I asked on the right forum. We have an online Bible study Group. Are these features readily available in Opigno or do we need to have it customized? 1) Save and continue/edit answers - anytime. This is because our lessons are not graded, but rather shared and learn from other participants. 2) Export the questions with answers to PDF, email or print. - so our participants can share their answers on their scheduled discussion meeting. 3) Automatically release each lesson on a weekly basis rather than show all lesson at once. This is because we don't want participants to look ahead and just focus on the current lesson. Thanks.
