Are there any workarounds for this? The current behaviour seems to actually allow for this on initial mirror column creation but trying to edit the column results in errors.
I am trying to generate a timeline from the first and last items in a group so that I can track workload across multiple boards. I don’t want to use sub-items as then they can’t be mirrored and the mirroring the board back to itself worked a treat:
video task 1 - jan 1st
video task 2 - feb 1st
video task 3 - mar1st-dec1st
want to create a line
video tasks = jan1st-dec1st - assigned to Bob
this would then allow me to plot multiple video task timelines from multiple boards in one view as well as review who is assigned to each of these
