I recently cancelled my Adobe CC subscription as the only thing I used it for was putting together vinyl LP mock ups.
On Photoshop ,the template I used has smart layers which when double clicked open a separate document and you can easily drop the cover art into, which then places the artwork into the PSD and applies the preset effects.
On both Affinity Designer and Photo I cannot see a way to use these smart layers. Double clicking (as I would do in Photoshop) does nothing, is there another way to work with smart layers that I've missed, or is this feature not available?
Hopefully the image explains what I am trying to get to work
