Sorry, English is not my native language and Google traductor helps me with the translation. If i did not misunderstand with the translation, you have a project and would like to see on your board the tickets of your project in addition to the tickets of other members of your project, but you do not want to add those tickets in different projects because the workflows of The different projects are different.
Sorry if I didn’t understand your need correctly.
In the event that if you have understood your problem, it occurs to me that the only solution that you can have what you ask for, keeping a little control over the original tickets but with total independence from the workflow of the other projects, would be using the “Follow-up Task” function.
Follow-up task will create a new task independent of the original one, but inside it will add a link to the original task.
You can “store” that new follow-up task on your Dashboard, and to know when someone completed that follow-up task, you will just have to open the task and see the link. When the original task is completed, a check appears automatically in front of the link.
Don’t worry, both tasks are separated one of other
Please let me know if I correctly understood your problem and most importantly, if my proposal can help you solve the problem in the absence of a native solution.
