Can Setnayan help us pick a date?

Yes. On Suppliers, tap your date in the date and place line at the top and choose Help me choose. Pick the month you are considering: its Saturdays appear, ranked by how many of your suppliers are free, with the best match marked. Once suppliers are in your build, only the days all of them can take are offered; a supplier who has not set a calendar does not rule a day out. Choose a Must-have supplier to put their free days first, then tap Use and the day to set it.
