Please add a way to make TravellingItem unmergeable. Sometimes it's really important.

Merge mechanics can probably be tweaked - is there a specific use-case where this makes a difference? (Perhaps splitting later, as normal pipes don't auto-split already merged stacks...)

mind giving some more context and exact use cases?

It will be very useful in this project.

if you're referring to https://github.com/RiftomeR/itemtraffic/blob/master/src/main/java/riftomer/itemtraffic/behaviours/PipeBehaviourBasic.java#L135-L164 then you probably need to use both PipeEventItem.Split and PipeEventItem.FindDest to manually split up the stack into sub-stacks, and then find a destination for every sub-stack.

Yes, i will do it. Thank you.

Just FYI the pipe event system hasn't had many addons testing it yet so please ping me somewhere on github (or in our discord) if it doesn't seem to do what you need it to.
