Set Theme & View for multiple Playlists in Big Box at once

📋 Summary

Currently in Big Box, themes and views can only be set individually for each playlist. For users with many playlists—such as auto-generated genre playlists—this process becomes tedious. This request proposes the ability to set the theme and view for multiple playlists at once.

🎯 Feature Overview

• Add bulk-edit support for playlists in Big Box to configure Theme and View.

• Option to apply changes to:

  • A selected group of playlists.

  • All playlists under a specific Platform or Category.

• Preserve existing per-playlist customizations unless explicitly overridden.

📦 Benefits

• Saves time for users managing large numbers of playlists.

• Makes it easier to maintain consistent aesthetics across related playlists.

• Reduces repetitive work, especially after generating auto-populated playlists.
