Can you modify default PG plugin frameworks?

Is there a “child theme” or something I can use to alter the default PG frameworks? Or if I change the files will they be overridden?

Specifically, my version of bootstrap has 8 spacers (ex: m-1 to m-8) vs the default 5. Thanks!

There isn’t an easy way to change the visual editor controls. You would have to add the extra classes through the Properties or Style panel, instead. Sorry.
