How to show post content excerpt in Archive List?

GD v2.0.0.24 with Genesis Theme:

I created own shortcode for GD Archive Item to show the post content just as excerpt:
[item-excerpt]

and a button to the place detail entry:
[item-profile-link]

Is this the right way to do or is there a better solution for limited excerpts and this button?

Can this shortcode for post content be limited and used as excerpt?
[gd_post_meta key=’post_content’ show=’value-strip’]
