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.
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.
Unwanted items can potentially underflow into positive (very unlikely)
