Group - Macro please

to group them... one has to first select...

despite this i want like this...

THE GROUP COMMAND IS ACTIVE UNTIL AND UNLESS I PRESS ESCAPE. 

In the active session.  if i draw the region, what are objects that are fall within that region are grouped.   Still the GROUP COMMAND is active... if i draw another region, does the same... group them.... like wise i want. since i have to group so many. once i made them grouped all, now i hit escape to come out of that command. 

hence please someone help in this regard.  i tried chatgpt but not working.
