LISP for breaking multiple polyline at 'insertion point' of multiple Blocks (AUTOCAD 2026)

[xenru]

I have multiple blocks(10 to 20) placed on multiple polylines in my map. I need to break the polylines of a huge map at the insertion point and join the vertices at the insertion point of the block.
Is there any LISP available to break the polylines exactly at the insertion point ?
I saw LEE MAC's LISP does something similar, but it trims the polylines at the border of the blocks. Shown in the picture (LEE MAC written)

Try this !? You can use POINT or Insert Point of block...
