Hello,
No, sorry but there is no feature for this.
This is more of a trend that is popular with sites using what is now a sort of old-fashioned method of actually forwarding users to a different mobile website. But now we’re working in an era of “responsive” web design where the goal is to get your website to display and scale down gracefully as the viewport size changes, no matter what the device is. So, it wouldn’t really work or be all too practical to have some sort of link that went to a full version of your site because you’re already viewing it; it’s just scaled down to fit the current viewport with CSS @media queries.
