Set account shorthand with 1password App

Hello, have a 1password account with a dash (-) in the name like a-b.1password.eu . When I added the account in the past with the cli a shorthand and of a_b was created (underscore instead of dash). With the 1password App cli integration the shorthand is not created anymore. Is there a config option to set a account shorhand that I missed?
I cannot set/export a environment variable with a dash (-) in the name like OP_SESSION_a-b. With the shorthand it was OP_SESSION_a_b which worked.

$ eval $(op signin)

You can either:
 - Connect 1Password CLI with the 1Password app to use the accounts you've added to the app and sign in using the 1Password app. Learn more: https://developer.1password.com/docs/cli/get-started/#sign-in for details.
 - Add an account manually with 'op account add' and sign in by entering your password on the command line. See 'op account add --help' for details.
 - Use 1Password CLI with a Connect instance by setting the 'OP_CONNECT_HOST' and 'OP_CONNECT_TOKEN' environment variables to your Connect host and token, respectively. Learn more: https://developer.1password.com/docs/connect
 - Authenticate using a 1Password service account by setting the 'OP_SERVICE_ACCOUNT_TOKEN' environment variable to your service account token. Learn more: https://developer.1password.com/docs/service-accounts/
