On our kanban board there is a 'Move to Done' button when all of the subtasks are complete:

Typically the next stage when the dev subtasks are done, is for the parent ticket to go in to testing, however the only option here is to move it to Done.
We would like to be able to configure this button so that rather than moving the parent to Done it moves it to the next workflow status, which in our project is Ready for QA
It would appear that this is not an option
Automation will not work for us as the developers need to complete a build first, often they wont do this until a number of tickets are ready, and so we need control over when we move it to Ready for QA
Are there any other options to achieve this? Could this be logged as an Enhancement Request to make that Button configurable?
