Can i use psd mockups?

[simonsanchezart]

How can i edit the smart layers? (open them, replace the image, save and see that reflected in the mockup with all the effects, transformation, etc.. like i would in photoshop)

 

In affinity photo or designer.

 

If it's impossible, will this be possible in a future?
