Saving the same style button for later posts

Hi,

I created a button for one of my posts, but plan on using the same style of button in pretty much all future posts. I can't find a way to save buttons that I've made with generateblocks. I don't think some parts of it can be done through css alone, since there's a logo. The site I'm doing this on is finerthingsbuyer.com. See further down on the page "https://www.finerthingsbuyer.com/top-5-supplements-everyone-should-take-for-excellent-health/" Also would like this in case I want to change the button style later.

I've searched the site and google quite a bit, couldn't find anything solid.

Thank you,
