Hi Venosa,
The sp portfolio itself does not support shortcode so that means you cant implement the shortcode for other gallery inside portfolio item https://www.joomshaper.com/forums/i-cant-insert-phoca-map-in-sp-portfolio-description
For this case I recommend you use easy image gallery https://www.joomshaper.com/joomla-extensions/sp-easyimagegallery , by using this component, you can create multiple albums then show up via front-end, demo http://demo.joomshaper.com/extensions/others/column2/sp-easy-image-gallery
