Use the send icon on each lineup to move it into one build, or favorite it to collect it in Favorites.
Every lineup card has a send icon next to the lock and trash icons. Click it and choose a different build, a new build, or Favorites. Send lineups from several builds into the same place and they're combined there, ready to put into lineup groups and export.
Favorites works like a build where nothing gets built. Lineups are stored there instead, so it's the simplest place to collect lineups across builds.
If you switch to “Compact View”, you can bulk send lineups to Favorites by favoriting the first lineup, then shift + Left Click on the last lineup you want to send to favorites, and it will favorite all lineups in between them (inclusive).
