Is it possible to add custom domain to Hosted Feature Service VIEW?

[SFM_WillBrewer]

I'd like to make a custom domain (pick-list) for a feature service that is a view. Will this corrupt the parent service?

The short answer is "no", you cannot edit a view in that way. You can try, but you'll notice the option isn't even available to you.

Hosted View Layer:

Source Layer:

If you attempt to manually edit the service definition on the view, you'll get an error message that what you're attempting isn't possible on a layer view.
