We work with a Kanban flow and make use of WIP limits for the different stages of our development cycle. Sometimes, an issue is depending on an internal person who's not available or an external party we have to wait for. This issue is then blocked and we set the "On hold" field to "yes".
At this point, the issue should not be worked on and thus should not be counted to the WIP limits set for the different columns. I'm not sure it's possible at this stage to do so. Is there a workaround for this?
