Delete game data but not DLC on PS4

[skud]

Does anyone know if it's possible to delete the game data from the PS4 HDD without deleting downloaded DLC? I have Arkham Knight which takes up a chunk of HDD space and after completion want to remove the main game data but don't want to have to download DLC again.

Can this be done?

Only way I can think of is to back up your apps to an external. Other than that, I don't think it can be done. Just also bear in mind that if you delete the game but keep the saves- you'll have to update again after you reinstall again.
