A way/module to display a list of Blocks assigned to specific path?
I not sure have I understand your question. 

At the picture below you can set it two path. Exmaple:

Page_1

Admin_Block_Page

Another one will be: 

Page_2

Admin_Block_Page

When you go to Admin_Block_Page, it will display block in Page one and Block in Page two.
