Octo will allow you to easily create assets in projects and assign issues to them, not to mention you get unlimited hierarchy for your assets.
Manage your assets across all Jira projects from a single place, via labels, versions/releases, and asset classes/categories!
Share assets across as many Jira projects as you want given your asset version can be linked to many projects (cross-project).
Create great reports by filtering assets by name, status, project and assignee.
