Problem: The user would like to have the parent post selected automatically in a form.
Solution: Regarding the first question, you will need to put the form inside a content template that is bound to the parent post. For example, create a view that will query the "Member" posts where the current user is the author, it should return one post if the user has already a post. Inside the loop, which is bound to that post, you can put the form and use the technique in the following article or the following similar tickets: - https://toolset.com/course-lesson/selecting-parent-posts-when-using-forms-to-create-child-items/#creating-forms-when-a-parent-post-is-preselected

The trick is to bind the post using a content template, using the item attribute, or inside a view's loop. https://toolset.com/documentation/programmer-reference/views/views-shortcodes/item-attribute/
