Is there a solution by now?
My daily workflow is:
Crop (and sometimes rotate) 1 to 1 ratio face portrait out of an image that has any size and resize it to 100 x 100 pixel.
Paste a watermark layer, position the watermark at the right lower edge of the image and export the result to a *.jpg file.
In Photoshop crop to a 1:1 ratio and resize the result to 100x100 pixel was a crop tool preset I made myself.
Up to now this is the only function I miss badly after coming from Photoshop. It's amazing what I could do with Affinity Photo but I am frustrated that such a simple task is not possible.
I am not experienced with macros. Would that perhaps be a workaround?
