Is it possible to create a custom Portfolio Kanban State field that is only applicable to one project?
Yes, it is technically possible to create separate Kanban states for separate projects.
Check the video towards the bottom of the screen on the how-to:

Ruchika - Thanks for your response. However, the how-to section that you referenced is related to User Story Kanban Boards.
I am looking to change a single Project's Portfolio level Kanban Board's Kanban State field which is a built-in field. I have found that any changes to this field impacts all Portfolio Kanban Boards in the Workspace.
I'm very sorry for any confusion. You are correct. The Portfolio Item's Kanban fields are only able to be edited on the Workspace level. I did see a recent suggestion for the ability to customize this at the project level on Agile Central Ideas. You can view it here https://ideas.rallydev.com/ideas/D4536 . When you have the time please visit it to add your comments and vote. This can help it gain attention. I'm sorry that I don't have a better option to provide. Please let us know if you have any questions.
Thank you for the clarification, Stephen. I see West has responded to your question.
