Can I see issues of different projects as a hierarchy style?

[jun lee]

When Epic issues are at a Project A, Story issues are at a Project B, and Change issues are at a Project C, I want to see from gantt chart like below.

EPIC 

 ㄴ Story

     ㄴ Change

However gantt chart shows like this.

Project A

  ㄴEPIC 

Project B

  ㄴStory

Project C

  ㄴ Change

Is there solution?
