That's an interesting idea; it might allow for more creativity.

Root Explanation
Nonsequential → It is formed from "non-" (meaning not) and "sequential" (from Latin "sequentia", meaning following). The word "nonsequential" means not following in a sequence or order.
Memory Tip
Think of 'not' ('non-') following in a 'sequence' — that's why nonsequential means not in order.
