Option to Add “All” questions from a specified category

Path: Lesson > Category Questions > Number of questions:[input a number]

Current option for Lesson:
“To Add any number of questions from a specified category. ”

Proposed Enhancement:
Option to Add “All” questions from a specified category.

Here we should have an additional option to add “All” questions (and not just a number).
i.e. All questions that are going to be in that Question Category.

Reason:
This will help in case where the number of questions in a “Question Category” may not remain a fixed number. Number count of questions changes with the newly added questions or deleted questions.

For example:
If a teacher added/removed some questions from that Question Category,
Now this made the change in the number of total questions in that Question Category.
Hence the teacher has to edit the lesson again.
Please consider the situation where multiple lessons are dependent on same Question Category. And the number of lessons is large.

Hope this simple enhancement to add “All” option should help to save time and bring accuracy.
