Can a Lookup list field point to web property bag?

Question

In my subwebs I have a 1 row list called "Details" that contains various bits of data that are meant to be web-level metadata. Image field, AssignedTo field, couple of string columns, etc.

On top of that at the root level I have a Content Query Web Part that grabs all subweb lists of type Details and displays this metadata in a grid.

What I would like to do is add a column to this list that returns the Title and Url of the site, however I don't want to duplicate data by creating a field to store it. I just want to return data that's already available at the web level.

Does anyone know if it's possible to add a Lookup column (or calculated) that will lookup a property in the web property bag?

Answer 1

No, you cannot create a lookup field against a web property.

If your skills in JS and Display Templates are up for it, you might already have access to web title and url in the ctx object.
