How can I customize my newsletter block so that there are multiple options for which email list to opt-in to?

I am hoping to build two different email segments and giving visitors the option to choose which email list they want to be added to, or if they want to be added to both. Specifically, a checkbox feature is what I'm looking for where checking at least one is required in order to submit the form. Is this possible with code?

Thanks in advance!
