Load images and change import settings

here are my current step
make image in photoshop
save as png
add into resources folder manually
chnage import settings to the following
texture type : advanced
read/write : enabled
Format : automatic truecolor

what id like to do

load them from seperate folder in application.datapath
chnage all of the import settings automatically

my question is how can i do this?

Simply use .psd format directly in the asset folder or subfolder then when you work on your .psd in photoshop you don’t have to change settings in unity again.
