You have a Powerpoint that is linked with an excel file lets call it File A, and there are 50 graphs in that file that you have linked in the Powerpoint in 20 different slides.

Now you have updated file called file B, with same graphs but updated numbers and now you want to edit link all the graphs that were linked with File A (all 50 slides) with File B.

How will you do it ?

because doing it link by link is so annoying.
I do have my own way of doing it in a single click that ensures everything edits properly in a click but am i missing something is there a builtin feature that can do it ?
