Gainsight identification id

Hello All,

We are currently using a user id (in my identify call ) during the signup process in our app, and once an account is successfully created I am using another user id in my post successful signup identify call. Is there any way to connect these 2 accounts on gainsight as it shows two different accounts on audience explorer. Is there any way to update the aprtrinsic user id and connect these 2 accounts?
