SSIS Data Flow: Join the auxiliar flow to the main flow

问题

The 'conditional split task' is like a If/Else behavior of programming language. But I don't want only these split behavior. I want to unite a recent opened flow( little scope ) to the main flow;

Using programming language as a example, what I want is this:

//this is the main flow
task1;
task2;
task3;
If( condition )
{
   //Now I have the auxiliar flow possibility
   taskAuxiliar1;
   taskAuxiliar2;
   taskAuxiliar3;
   taskAuxiliar4;
}
//Now a single main flow again** ( I want do this )
task4;
task5;

What I can do for resolve this without lose performance inside the data flow?? I don't know if merge/join tasks are good for that, because I read these tasks are bad for performance. I want a auxiliar flow with a little scope to do few things, and after that unite again to the main flow.

Best Regards, Luis
