In IDM it can be

   ~H- -> W-,~X

or

  ~H- 0> W-, ~H3

or

~H- -> 2*x

which gives you both processes. But these processes  can be closed
kinematically. Then one has to  test 1->3 type of processes.

"Exclude diagrams"  during "Enter process" can not exclude diagrams for
1->2 process because here virtual particles are absent.
