Luis, you cannot include the same physical program multiple times in a flow. If the program is stored on the server file system and referenced from your flow, you can include multiple code nodes that reference it with %INCLUDE -- of course.

Also, you can reference the same program multiple times by including it in an Ordered List (File->New->Ordered List). Unfortunately, you can't reference a single program multiple times in the *same* ordered list, but you can define multiple ordered lists in your project, and reference that program in each list you create. This might help you to define the sequence of actions that you want.
