Be able to import geometry data from other geometry

What do I mean by that In Houdini, it is possible to easily import absolutely any geometry state from one object to another using node Null and Object merge. In this way, you can import a grid in absolutely any state, safely, absolutely anywhere!!! and then you can safely work in geometry!!!

How could this be imagined and implemented in geonodes?

It would be possible to create a new node called (Again in the context of naming Geonodes) Store Geometry and import it into another object called Import Geometry. This way, you can safely import the geometry state inside the Geonode!!!
