Is it possible to define multiple custom models to choose from in /model?

Hello,

When using AWS Bedrock and having defined a custom model ARN with the ANTHROPIC_MODEL env var I see this model appear under /model in Claude code. However, if I want to switch to a different model (e.g., if ANTHROPIC_MODEL is set to Sonnet but I want to switch to Opus) I would need to find and paste the new model ARN calling /model <model_arn>. This would be much more convenient if there was some way or location to place different "defined custom models" or such that these could be more easily navigatable from the /model command within Claude code.
