I am not sure I can help here as I only have CS6 and I believe you are talking about the Camera Raw Filter in CC?
If you can create an action that does what you want when the SO is opened then there may be a workaround.
What you would need to do:
Create the action when the SO is opened.
Save the following code in the Applications Presets/Scripts folder as a plain text file with a ".jsx" extension
N.B. You need to amend the code with the ActionName and the ActionSet of your action (it is case sensitive!)
[code]
#target photoshop;
app.bringToFront();
main();
function main(){
if(!documents.length) return;
if (activeDocument.activeLayer.kind == LayerKind.SMARTOBJECT){
executeAction( stringIDToTypeID('placedLayerEditContents'), undefined, DialogModes.NO );
//Amend ActionName and ActionSet to suit NB: these are case sensitive!
doAction('ActionName','ActionSet');
try{app.activeDocument.save();}catch(e){}
app.activeDocument.close(SaveOptions.DONOTSAVECHANGES);
}
};
[/code]
Now in your original action you need to call the script (instead of opening the SO)
This is done via fly out menu of the action palette and select "Insert Menu Item" then File - Scripts - select the script.
The script will open the SO, run your action update/and then close the SO.
