I want to know if it is possible to send, visualize or/and modificate an Issue card in more than one Kanban board, these kanban boards belongs to a different projects and sprints! At the beginning I thought that this task could be done with epics but I do not understand at 100% the functionality of the epics!
If your answer is yes, please help me, I want to know how...and if your answer is no, please let me know! 
Happy new year BTW!
