Specify insertion point:
It has always been that way, and I have always thought the message should be worded differently, because the definition may not be duplicated -- it's only a Block name that's used in both the current drawing and the stuff being brought in. I'd prefer something like:
Duplicate Block name WHATEVER involved -- using this drawing's definition.
Besides other suggestions, another way you can do it is, instead of using Copy/Paste, to WBLOCK the Block definition from the first drawing to a little drawing file of the same name as the Block, and redefine it in the second drawing in the process of INSERTing it from that file:
-INSERT WHATEVER=
Note the hyphen before the command name, and the equal sign after the Block name with nothing following that. That means it should look for an external drawing of the same name as the Block. If WHATEVER is already a Block name used in the current drawing, it will ask you whether you want to redefine it.
EDIT: And, if instead of Copy/Paste operation, you call up the Design Center in the target drawing, and bring up the Blocks list for the source drawing, there's the option to redefine [with or without Inserting one, too] right there:

and you don't even need the source drawing to be open, as you do if you Copy/Paste. If you do Copy/Paste multiple objects at once, including multiple Blocks that you want redefined, you can use this afterwards with the Redefine-only option to update them.
