"Professionalize" hierarchy of sources (LinkedIn>IG)

I connected both my LinkedIn and IG accounts to Dex. When merging contacts, Dex prioritizes the IG profile picture and name over that of LinkedIn. My principal use case is professional, and I don't want Dex steering me toward prioritizing the personal/social profiles of my contacts. Also, by not prioritizing actual First/Last names of contacts from LinkedIn or Imported Contacts in favor of Instagram usernames and profile pictures when merging, my contact list becomes much less searchable and more frustrating.
