Nevermind guys i've solved it!
For those of you who need it, just set the link on the image block setting to be "On Image" instead of on button and then insert a text link in the image title. You can then style that text link to look like a button with this code.
You can change the 'p' to h4/h3/h2/h1 depending on your needs.
p a {
font-size: 1.2rem !important;
text-decoration: none !important;
color: #fafafa;
background-color: transparent;
border: solid #fafafa 2px !important;
padding: 20px 30px;
margin-top: 1.5em !important;
}
p a:hover {
background-color: #fafafa;
opacity: .93 !important;
color: #262626 !important;
}
