Research direction

Investigate the existing mask directive implementation in the repository's source code (likely in JavaScript). The goal is to add an optional 'prefix' attribute to the mask directive, similar to how suffixes might be handled. Check for any existing patterns or discussions in the comments. After implementation, update the documentation and add unit tests.
