I have a problem when I intend to associate class 3 with an association 1

Dear Sirs: I'm using umbrello to make my classes diagrams, so far
everything goes fine, but I have a problem when I intend to associate
class 3 with an association 1 that comes from class 1 and class 2

_____________                                          __________
|    clase 1  |  --------asociacion1--------------| clase 2 |
--------------------              |                           ---------------
                                  |
                                  |
                                  |
                                  |
                              __________
                              | clase 3 |
                              ---------------




I'd like to know if this can be made with this software or I should
wait for this feature to be possibly added in a new version of the
software, I am in knowledge that this can be done in paid softwares
but it's not my intention to use them in my project
