Component diagram/draw multiple usages of a provided interface in the same diagram

Hi, I have three components in a component diagram, each providing the same interface ("lollipop-bullet"). I also have a component which can USE this interface of each component. But I can only draw one "usage" line with the corresponding "lollipop-bracket" style. For the others, Astah says "this usage relationship already exists". How can I draw this? Is this scenario forbidden in UML, and if so, what is the recommended way? Thanks for any hints Ingo
