We have the ability to turn off "Other books in the series" in our Syndetics settings which turns off the gray covers for items not owned in that section, but unfortunately we have no way to turn off just the "Similar Series" section of "You May also Like" without also turning off the "Top Picks" for individual titles in the "You May also Like" section. We would like "Top Picks" to be separate from "Similar Series" in the settings for "You May Also Like" so we can turn off one without turning off the other.
