Ability to create a descendent of a multi-line flashcard

Problem Statement:

Currently, it appears that creating a subrem whose parent is a multi-line flashcard is not possible.

Why This Feature is Important:

In certain cases, users may need to add subrems that depend on the complete set of answers from a multi-line flashcard. During review sessions, it is beneficial to see the entire context, which includes all the answers from the card.

Proposed Solution:

Enable the creation of subrems that have the entire multi-line flashcard as their parent. This would allow users to:

1. Add additional information that is directly linked to the complete set of answers.

2. Review the subrems in the context of the whole multi-line flashcard during study sessions.
