AI Generative Credits offerings not suitable for occasional users

The current AI Generative Credits offerings are not suitable for occasional users of AI features. I use the Adobe Photography Plan (20GB) as a hobby. I would like flexibility in purchasing AI Generative Credits. I would like to be able to purchase them on demand. AI Generative Credits should be available as long as my Adobe subscription is active, without the credit counter resetting to zero each month.
Are there any plans at Adobe for this?
