Original request description:
As a person responsible for running the project I need to have the tools aligned with my projects' structures. My projects are organised in a large hierarchical groups of components. I need to be able to assign the JIRA issue to a whole group of components, as well as individually to any component within the system and be able to interact with issues in JIRA based on this assignment - i.e. all issues for component group, including both issues which are assigned to group as well as issues assigned to individual components within that group.
