As far as I can see, this is not an option - manually updating this field after some staff turnover is time-consuming. Can an option be added in the same way that you can batch update the primary staff assignment to also be able to update the secondary staff associated with a request?
I just came on to log for this too - and saw one had been raised back in 2017.
Can we please have a look at this suggestion and implement into the sky interface? updating 1st staff when they change it super easy, but 2nd staff is so time consuming doing it individually. Its such a quick fix that will save so much time.
Thanks
