How to set custom Splash Screen while loading big objects?

Before UE 4.14, I can set Steam VR’s Background Image to show my own loading image.

Then in 4.14, it seems UE take over it and there is a function named SetSplashScreen .

But after I using that function to set my custom splash screen, it only appears when switch between levels. If the game is stuck by loading a big object, the default splash screen (with a UE icon at the center) shows.

Is there a way to show my custom splash screen at every moment the game is stuck?

Any help is appreciate!
