I currently have a Gallery (background below), that populates another 'pre-view' Gallery. The User can select a number from the Dropdown, which populates information in the background (hidden fields), some of which appear in the preview. The User can choose as many Questions as necessary. These are saved in a Collection. The preview Gallery is based on the Collection.

My desire is to have the 'Question No.' and 'Comments' provided be collected and appears on a single line in the SP list, rather than multiple lines. The top example below is a example of the SP list. Both times, where multiple questions were chosen only the 'last' chosen is shown in the Question No. column.
The preference is to have all the Questions No.s chosen appear comma delimited. Likewise any comments written should appear together in the same field comma delineated. - as demonstrated in the lower example (I made in Paint).
