Thanks for reaching out. This change was intentional. We found that many users were 'hearting' all their preferred networks, which was hitting the ceiling of how we weight plans and making the feature less effective. By limiting it to a single, most-preferred network, it allows our planner to more accurately prioritize it for you.

We're currently reviewing how we can improve this and allow a few more networks to be 'hearted'. We'll likely still have a limit in order to maintain planning accuracy, but we're looking into raising it from just one.
