Pre and Post Service Option for Times

In Planning we have our time setup for all items, pre, during, and post service. When we print out the order this shows our timestamps as off because the pre and post-service times are part of the overall order. Can there be a checkbox or something added that would make pre and post-service items not part of the overall time calculations?

This would be a decent workaround for my dilemma of not having customizable service "times" types. We are stuck with just call time, rehearsal, and service. But with pre- and post- service items we could just include pre-service items in the order.

This is the only thing not making Planning fully useable for us. Pre-service items such as the AV team starting the countdown, different teams knowing when briefing/times take place etc, these are all key to keep the team on point. So the ability to choose the 'start time' would help but if not, just marking items as pre-service or post-service could work. Thank you.
