List styles and the template

I have a couple of questions about these:

I understand why normally, list styles should not contain more than three levels, preferably not more than two. However, a plan for creating a database could use an outline format. The odd levels contains the questions about the database in secessive more specific ones. The even levels contains the answers to the odd level questions directly above it. This is going to take much more than three levels to describe the desired database in detail. So, any suggestions as to what the characters should be for the levels below 3 going beyond level 5? (This information I need for the chapter on planning/designing a database.)

The template contains list styles which we no longer use, the ones containing, Start, Continue, and End. Is there any reason why these have not be deleted from the template?

The paragraph styles for lists with Start, Continue, and End in their
names are built-in; they cannot be deleted. They can, however, be
hidden and perhaps they should be.

I did not realize that, but it does make sense. Normally, I limit the styles I see to what is in the list "Applied styles". I would not have noticed their existence except I need more than three level of list styles for the Planning/Designing your Database.
