Hello there, @ZSolve. I understand the confusion given that you're from QuickBooks Desktop and navigating through QuickBooks Online can be a whole lot different experience. No worries, I'm here to clarify things out and share additional information.
When creating a custom field, we only have the option to choose a specific category ( Customer, Transaction, Vendor, Project) and select forms where we want the custom field to appear. Thus, the ability to associate it with a specific customer is unavailable.
I can see how you would want to have this ability and like you, I also think that this would be a great addition to QuickBooks Online's features as this will benefit not only you but other users as well who's been needing to have a custom field that can be associated to customers. No worries, I'll take note of this and ensure to notify our Product Engineers.
Alternatively, I also recommend sending your own feature request so they'll know that this is something you personally need and might encourage other users to vote for this as well.
