Often times it is hard to draw with the under image at 100%, I changed it to 20% and messed with all the display quality buttons and check marks but nothing I do will make it show the opacity of the image unless I render it

Do I have to go into photoshop and reduce the opacity of the image, save it, and then import it into anime? Or am I missing an obvious setting that will allow me to see the reduced transparency while I am working on the layers above the picture?...
Thanks
