Hi Jules and welcome to the forum and Dj’ing…
So not too familiar with the DDJ 200 but I don’t think it has an actual dedicated hardware Loop or Saved Loop pad so it will have to be done through the app it self.
To resolve your issue, go to the Loop section in the app and go to the Saved section and then de select that saved loop.
Then when you need them, go to the saved loop and select it again…It should be highlighted in the beatgrid for the next time .
