At our company we are working on 5 different applications with its own UX/UI. For each application we have a separate Foundation file (containing colors, icons, font types, etc.) since most of it differs. However, we do ‘cross-use’ icons.
Is it possible to setup a separate icon library containing all icons which will be inherited to the different foundation files? So when we change Icon X in the icon library, it will be changed in all the foundation files in which it is used? Or would you suggest to strip the icons from the foundation files and use a separate icon library?
Currently we have to change it manually in the different files which is obviously is not the best way to do it 
Advice is very welcome
