Automate Tag in Mailchimp?

Hi there,

I use a Squarespace email form + MailChimp to capture key data about those who sign-up to my mailing list. To take a step back, my website is an architecture publication and on the form there is a dropdown that has 'What best describes you?' with several options including; architect, builder, student, architecture lover, etc. This data helps me when I communicate with architects and potential advertisers as it tells me who my audience is.

My email list is small so I've been manually tagging each contact, but I am hoping the list will grow so large that it no longer becomes viable to tag each one myself, so I'm wondering if it's possible to automate this process through MailChimp. Has anyone done something similar? Below is kind of the flow I hope for;

Land on page > fill out form with email, first and last name > select 'architect' from dropdown menu > signs up to mailing list > 'architect' tag automatically applied

Is this possible?

For reference, my website is www.thedesignemotive.com, and the main forms are like the one underneath the video here;

Any chance you figured this out?

I think I figured out a work around.  By using an embedded Mailchimp form, I am able to add the code to the site which will automatically collect the email.  I'm not certain, but I'm pretty sure that from there it's pretty easy to automatically apply a tag to that since its already collecting it within Mailchimp.  Hope that makes sense.
