[FR] Action of Issue to promote to existed User Story's task

[JAkutenshi]

Hi,

The problem
In a project we have a Sprint and fixed count of User Stories in the Sprint. But our tester create issues with GitLab that can be bugs and enhancements too. An issue can be promoted only to User Story, but actually enhancement Issues are more like tasks for existed User Story.

the proposal
I propose to add "Promote to Task for existed User Story" for an Issue.

Probably I have misunderstood the workflow between Issue <-> User Story <-> Task, but it's looks like workarounds: just duplicate content of an issue to new US's task. And manage 2 entities: status of Issue and Task -- both.

Thank you.
