Workaround to assigning subtasks to another team/project

[Rebecca Stafford]

I've seen the question asked previously regarding IF there is a way to assign subtasks to other projects/teams and the answer was that it was not possible.

Has anyone found a workaround for this??

Here is my problem, our organization is made up of product teams and then a core teams and data teams.  Many of the product teams have dependencies on the core and data teams to meet the A/C of product stories.

The problem is that we can't take advantage of reporting or see progress of completing a story based on the completion of subtasks
