Retool Postgress SSL certificate

In the UI for setting up postgres resource, I am currently required to upload a certificate/private key and ca cert. I've seen in screenshots that these upload controls can be text areas (mabey this is an older design, i'm not sure), the text area allows for pasting the certificate content - and presumably using exposed environment variables. Is there a way to get this UI - as it will allow me to use an exposed environment variable containing the the pk/cert and ca.
