Hello,
I’ve passed your suggestions to our developers and I hope this will be added in one of next theme updates.
For now, to display projects of the portfolio on the page, please try to use Post Grid or Post Masonry Grid http://prntscr.com/fkel1n http://prntscr.com/fkelec, select design http://prntscr.com/fkemf8 or create it by yourself http://prntscr.com/fkemjh https://vc.wpbakery.com/video-academy/grid-builder.
