Feature Request: Add to "Merge Tags" list

Hello, I am requesting new functionality.

Similar to how we have the “Add to Preserve Tags list”, I would like to have a “Add to Merge Tags list” option.

There was a new function recently added to manually select fields to merge original/new values, however it would be useful to set certain tags to always merge values.

My specific use case for this is to merge old/new genre tags, but could be useful for other tags.

Thanks!
