Blog Subscriptions / Form List

Is there a way to add a blog subscription button to the main page? I have a Subscribe form that I used for visitors to sign up to receive updates/blogs. With the addition of the blog email subscription and features, I now have two lists.

I am currently using Mailchimp for blog updates/emails. It would be great to convert the Form on my site to "Blog Subscription Signup" and save a few steps by working on strikingly for all actions...and one master contact list to communicate.

Any insight is greatly appreciated.
