While on auto layout, is there a way to set a single component to always take up 60% of art-board's width while setting every component to be "fill container"?

So, let’s say there are two cards horizontally on landscape art-board with auto layout. Both are set to “fill container”. This makes each card to take up 50% of the art-board. I need one on the left to always take over 40% and one on the right to take over 60% of art-board’s width while both are staying “fill container” so they can be responsive.

Is there a way to achieve this?
