Create vault entity with user okta email

Hi, I have configured okta oidc.

vault write auth/oidc/role/default \
      bound_audiences="XX" \
      allowed_redirect_uris="http://localhost:8200/ui/vault/auth/oidc/oidc/callback" \
      user_claim="sub" \
      policies="default" \
      groups_claim="groups" \

When user authenticate and logs in Vault, a entity and aliases is created -
Entity -
Name - entity_9e2ecfa8

and aliases
Name : “openid value”
Do we have way in which instead of openid value I can add email id, if not is possible to add email to metadata in aliases ?
