Can Planner positions all be set to same date?

I am using the planner in day mode with sidebar on top. The positions represent different Vehicles, and Items the stops for the day based on Geolocations. Each position is then representing the same day. I initialize the planner to the current date, editing the individual items shows the correct time, however the positions increment the date. This makes sense as day mode. How can keep the same date for all positions?

What is the setting for Planner.Mode.PlannerType?
You might have to set this to plCustom

plDay So I understand why it is incremented. Is there a way to change that?

Yikes! Just tried that and all dates are the infamous 1899 and no more Time periods in sidebar and all items are in the first position

You could still set it as plDay and override the Planner.OnPositionToDay and return a fixed date for all positions via this event.

Exactly what I was looking for!
Thank you so much Bruno

BTW I did read through the manual before posting, I know you must be very busy

For anyone with the same issue... Take care to make sure the Time part of the date is striped off or all items added will have the time offset added to the begin time
