Cross spaces summary

[Mike Kondrashin]

Is there a way to create a page with a summary of a field across multiple spaces? To give a bit of a context: we use spaces for projects, so each space will have a page with a summary of the project setup. Let's say we have a field A which describes certain details of the project setup. Now I want to have a separate page dedicated to field A, that will list all projects, where field A is set to Yes/Not blank, etc. 

Is there a way to create a page that will look up some value across multiple spaces?
