Hello,
A workaround that is used is to create a task with one minute duration
as the predecessor (F to S) to the task you wish to move. Create a new
calendar (Tools > Change Working Time) where the only working time
Monday through Friday is before the start of your working day (7:58 for
example.) Assign the one minute task calendar to the one minute task.
This will force the predecessor task to being the next working day at
the start of the day.
I hope this helps. Let us know how you get along.
