need LINE TRACE BY MULTIPLE CHANNELS _ to make it simpler just same as for LINETRACE FOR OBJ array

There would be great some little costemtic improovements for BP to have ability to LINE TRACE BY MULTIPLE CHANNELS as LINE TRACE FOR OBJECTS HAVE, it would be handy to avoid multiple raycast instead if your project is dependent on channels.

It is intended that if you are using ‘trace by channe’, you only use a single channel. This way of tracing allows the objects to decide on their response to the trace. I’m not sure how it could handle the case where the object wants to ignore one channel but block another…
