I used `echo -e` in a single `RUN` line to create the suppression file, which simplifies the process and avoids the need for multiple subshell invocations. This keeps the script efficient and easy to maintain.  Additionally, this approach is better because it minimizes changes to the file, unlike when using `split-file`. What are your thoughts on this approach?
