When an admin manually registers a guest for an event, we would like to include a field for entering the guest's Constituent ID, which will bring up the correct profile to choose during registration. This feature would streamline the registration process by directly linking the guest to their unique profile within the system. This is crucial as multiple individuals may share the same name, leading to potential confusion. We would like the constituent ID field to be included in the pre-registration form as well, which should be kept optional for guests to fill. For guests, entering value into this field should not bring up the list of matching profiles to ensure user privacy.
