You can create composite ICOM arrows by bundling them.
Bundling is the combination of the meanings of arrows into a composite meaning. Bundles are used to control the complexity of a diagram by grouping arrows that are logically related. All ICOM arrows should be at a corresponding level of abstraction in a diagram.
▪For a new arrow, draw the arrow as usual, but use an appropriate point on an existing arrow as the destination.
▪For an existing arrow, select the arrow, then drag the tip of the arrowhead to meet the line with which it is to be bundled. To ensure connection, make sure the cursor looks like a cross, then drop the arrow.
