Method to update blocks and nested blocks

[Sambuddy]

Is there a method to update blocks and nested blocks (dynamic and/or annotated without losing their position, visibility status, and annotated values: Tag/prompt/default values) based on new blocks that will contain in a folder (source files)? New blocks have the same block name as old ones. The cad block files within the "source" folder have the same name as the old block.

Dynamic blocks have stretch or rotation properties, example: block is stretched to 2100mm and rotated to 30 degrees.

1) is it possible to obtain this kind of sophistication? 2) How would I run this routine without opening the drawing and that select the drawing files?

Thanks
