Our application has complex flows which calls multiple activities and Data transforms. There are very few assignments shapes. So while tracing from one assignment to another multiple rules are called making the tracer file too big. There are certain activities which are called multiple times with different parameters in the flow. As we are aware these activities work fine we want to stop tracing these activities. So that when developers are tracing they dont see these activity steps on tracer. We can not switch off tracing all actiivties or actiivty shapes as there are some activities we want to trace. Only thing is we want to skip 1-2 activities which are too big and we know are working fine.
