As a whole, yes it should be possible, but how to do that will really depend on Astra and if you have any sort of page builders included and whatnot.

They may have settings regarding custom content types that they can detect to also output that information. I confess I’m not knowledgeable enough to say for certain if Astra is child theme friendly or if they try to handle everything themselves via settings and options.

Their support would definitely know more than me, otherwise it’d be a case of duplicating the right template files and modifying as needed.

I have already added a child theme. so that is not an issue. But i’m not sure which template files i need to modify in order to archive same results on CPT as blog post.

Any idea?

This will be your best tool: https://developer.www.ads-software.com/themes/basics/template-hierarchy/

single.php would need to be reviewed and potentially duplicated and renamed to single-my_cpt_slug.php.

I say potentially because the template file may have conditional checks for what type of content is being shown, or it may have Astra-specific functions being used to display things, for which you’d want to reach out to them for more information.

Any news here @leonzeschke or are you still having some questions?
