ignore links by data attribute site-wide?

Hi there! Under the Exceptions tab, I’m choosing to ignore a set of links by class. There’s a type of link throughout the site with a data attribute “a[data-lasso-name]” that I’d like to also ignore (or alternatively, force to be an external link)

What’s the best way to add this data attribute to my list of classes I’m asking the plugin to ignore?

Can I do it within that field under the Exceptions tab, or do I have to create an action / filter in my theme file? And if it’s the latter, how exactly do I form this action / filter?

Thanks in advance for any tips / help.
