Hi, Dave
from the picture it tells us we could combine entities from different routes( more than 2 ) into 1 entity. and the batch quantity of each route can vary.... so for example,
we can get 1A,2B,3C,1D,etc..............and combine into 1 X
and the batch quantity can also use Expression, not necessarily a constant.
the quantity of combing routes can be changed if you pull the black rectangel below....
Sometimes we don't want "box in box" concept, we only need to batching different quantities of entity type into 1. and then separate at some point just as when they are batched together...
current construct of Cominer can only bacth two routes, due to its parent/member logic..
