Hi,
It is not possible at the moment, but you can use the default [portfolio] shortcode https://en.support.wordpress.com/portfolios/portfolio-shortcode/ use its parameters to separate them and use the text widget to put the shortcode in the homepage widget area in Appearance -> Widgets,
After that use this in the functions.php of your child theme, this will add support for the text widgets to run shortcode.
add_filter( 'widget_text', 'shortcode_unautop');
add_filter( 'widget_text', 'do_shortcode');
PS: You can request the featured request here: https://colorlibsupport.com/t/shapely-feature-requests/
Let us know,
Thanks,
laranz.
