can i make a combiner precess depending on the item type?
exemple: i have 3 types of items.
the first one has 3 subitems
the second has 2 subitems
the third has 3 subitems
that means i have 3 inputs in combiner but once the second type of subitems arrives the combiner wait the third item which it doesn't exist how can i make condition on input that makes the combiner process depending on the item type?
