[Theme Horse Support Team]

Hi thecedarsrc,
We are sorry for this. We don’t have this feature So it needs code customization. We don’t know about the gallery plugins too. We have our own gallery in our pro version Which you may check in our demo site too. You may increase the excerpt length by changing it in code because we recommended you to never change the code because if you customize the code then while updating to our new version all your customization code will be lost. So always make the child theme before customizing the code.

Thank you!
