Blueprints for pages without URL possible?

Thank your for the quick reply.
Today I also found this thread that seems to describe the same issue: Disable public URL for pages
I think i found a solution for my project now, but it feels a little bit hacky to me.

In most of our projects we have resources that have no specific independent URL an get reused on different pages (e.g. contact cards, events, tickets, external links, …). Also when thinking about a headless setup where resources can have different routes dependent on the application they get required by (Website, App, …) the described solution maybe does not scale very well.

Do you know about plans to add a feature related to this topic? Since in the other thread you said:

there is no container concept (yet)

If not, what would be the recommended way to make a feature request? Github issues or should i use https://kirby.nolt.io/?
Or maybe do you know about an existing feature request? I just found this request that seemed somehow related Kirby Builder: Global / Reusable Blocks#132
