Force DOI on a newline in reference list

I'm using biblatex for my citations (using xelatex). This is the relevant code to invoke the reference list:

\usepackage[backend=biber, style=authoryear, doi=true, firstinits=true, maxbibnames=99]{biblatex}

My reference list looks like this:

Now, I would like the DOI to always drop to the next line. I've read some questions that also refer to the URL, but I do not mind the URL. It's only the DOI I care for, which I want to permanently force on a newline. I've tried this:

\DeclareFieldFormat{formatdoi}{\newline #1}

As a shot in the dark from something I saw related to the URL, but this does not work. I see some fairly large and complex possible solutions, but I feel this should be possible in a one-liner (or something short, at least). Is there a way?
