Character Tracking/Spacing in Buttons

Hello! I don't remember having this problem before now, but I can't seem to find a way to adjust character spacing on buttons. My current client prefers a lot of tracking in their design and compared to the rest of the site, the button text looks pretty squished. Tried to get there a few ways through Site Styles but don't see the text spacing slider anywhere for buttons.

Thanks for the assist!

Try adding this to Design > Custom CSS

div.button-block a {
	letter-spacing: 5px;
}
