Custom blank slide at start of each song/item

When adding a song or item, it is possible to select a blank slide be added
Can this blank slide be a custom background display for this slide only (But not on song lyrics)

Blank slides can be turned on for songs and Scriptures in the Settings. It will match the background of the song and cannot be set to a separate background.
For that, you'll need to add a media slide item above the song.
