Choose which Exchange contact folder(s) to sync to phone

On Office 365, my folder structure is this: My Contacts [container, not a folder itself] - LinkedIn - Contacts - Contacts2 - Skype for Business Contacts -... I want only contacts from my "Contacts" folder to sync to my phone, and not from the other folders. Is there a way to achieve this? I don't mind installing a sync app, but don't want to install the Outlook app. I have seen a hacks using Categories to only show selected contacts in the Contacts app on the phone, but this has 2 problems: 1. I would have to add a Category to every new contact I make in my Contacts folder to get it to sync, which is very error-prone. 2. I think it still syncs all of the contacts from every folder, using phone space and sync bandwidth. Any help is much appreciated.
