I have defined a content type in content type hub. I would like to use this content type on a site (other than the hub) but also to extend it with an additional (lookup) column. Is it possible to do so and to preserve the synchronization of the content type with the content type hub?
The reason why I need this in the first place is because I cannot create a lookup column within the content type hub and make it work in another site collection. I've read somewhere that if you create a list (the one the lookup is targeting) inside the content type hub site, make a template from it and then recreate that same list on another site, that the lookup would work. But it doesn't - I expected this, because the GUIDs don't match.
So is there a way to solve this?
