Set number of columns for Hero Quotes & Quote Grid Widgets

Hi,

I would love the option to set number of columns for the Hero Quotes & Quote Grid Widgets.
I know they are responsive to screen but our embeds would look a lot nicer if I could set columns.
Screenshot added for example on desktop. I have 6 testimonials to embed on an area of our WordPress page. I'd love to be able to set a max of 3 columns so they show in 2x lines.
Thanks,
Ellie
