SimEvents: Combining multiple entities on same port with Composite Creator

Hello In Simevents, how can I use the Composite Creator to combine several instances of the same entity. Example: I have 2 input ports on the Block. I want to combine several Spanners into one ToolKit. The ToolKit is the main entity on port 1. On port 2 I want to add 4 spanners in one go, without having to define ports for each. I would like the number of spanners to be set somewhere else in the model and it will determine how many spanners will be combined with the ToolKit.

Another example: a supermarket wants to promote items by combining them. The new package will contain 1 bottle of shampoo and 3 bars of soap.

Many thanks
