You remove the return line from the reservoir and route it to a bucket, with the front suspension hanging, then turn the wheels side to side to pump all the fluid out. Then hook everything up, refill and bleed. There’s videos out there, maybe @iamdub can link one.
This is exactly how I do it. I watch for it to start sputtering, shut it off, add more fluid, start it back up and repeat. Usually takes about a full wasted gallon before what's coming out looks identical to what's going in.
Here's the first video I Googled. This Hotel WiFi is kinda slow, so I just skimmed through it. Not totally sure of the content/relevance:
