v15 Cache Clip Source?

Not that it worked flawlessly... but I've found cache clip source often useful, especially with 8k Helium. I've been unable to find it in v15; is this gone for good or am I just blind and lost?

Ok after opening an project from v14 that had cache clip turned on and seeing the red/blue cache indicators, then going up to see fusion output cache checked i'm guessing this is the 'new' wording for clip source caching? It's confusing at best...
