Is it possible to link tasks between separate lists / board items?
If a task is common between two columns, can it be updated / completed in both areas at the same time?
Hi @pixelpicnic and welcome to the Forum!
It is possible to multi-home a task in multiple projects; this way, any modification you make to the task will be reflected in all project it was multi-homed in.
With that said, it is not possible to have the same task in two columns within the same project; one task can only live in one section/column of the same project.
Hope this helps! Please let me know if you have any follow-up questions!
