Suggestions on how to manage different projects sharing the same frontend codebase

[Virginia Morrone]

Hi everyone, 

my team and I work daily on Jira since ever. 

We are now experiencing a new organizational structure where we directly manage two different projects which share the same frontend codebase. 
We already have a kanban which filters for both projects but I was wondering if there's any other feature/option that might help. I want to avoid the opening of a ticket for frontend in both projects or to add the criteria "this also applies to the other project" or viceversa. 

Any suggestion? 

Thanks in advance!

@Virginia Morrone It all comes down to how you run your projects and the processes that you have in place for the shared codebase.  Can you provide some insights into how this works?
