Hey Again,

I am afraid you cant import a single portfolio page however you can import the ascend content.xml file manually to get the pages . 

You can also copy paste its vc code in text mode and then switch back to Page Builder :

[vc_row type="full_width_content" vertically_center_columns="true" bg_position="left top" bg_repeat="no-repeat" text_color="light" text_align="left"][vc_column width="1/2" animation="none" column_padding="no-extra-padding" background_color="#151611" background_color_opacity="1"][vc_column_text]<iframe src="http://player.vimeo.com/video/23711782?title=0&byline=0&portrait=0&color=ffffff&autoplay=1&loop=1" width="549" height="309" frameborder="0" allowfullscreen="allowfullscreen"></iframe>[/vc_column_text][/vc_column][vc_column width="1/2" animation="none" column_padding="padding-4-percent" background_color_opacity="1" background_color="#fe4641"][vc_row_inner][vc_column_inner width="1/1" enable_animation="true" animation="flip-in" column_padding="no-extra-padding"][vc_column_text]
