When creating a thing in Bubble, can I only add one field per step?


Hi, so I'm trying to connect Mailchimp to Bubble and when a new subscriber is added in Mailchimp, I'm trying to create a thing in my Members data type in Bubble. I can't find a way to add more than one field in a step. For instance, the thing in Bubble that I'm trying to create has a First name, Last name, email, and about 20 other fields, however in the Pabbly Connect step I only see the option to add one data type one field name, one field value. Surely this can't be the case and I'm overlooking the obvious so any help would be greatly appreciated.

Thank you.
