1) Logistic network doesn't show items in transit as available potentially causing another delivery in a bot unloading station design.
2) If bots try to pick up more than available the number becomes negative, which is LTN's trigger for requesting this amount.
To combat these effects I put together this signal filter.
Green sets the amounts of desired items as usual for LTN with negative sign.
Red (optional) filters signals entirely.
Pro:
Only positive signals not set by in any cc are displayed.
Signals set in green cc are only shown when negative to prevent pickup/delivery circle.
Con:
Unwanted items can potentially underflow into positive (very unlikely)
