Linked Excel Object in Powerpoint wont update when showing in slideshow
===

I'm new to this and basically what I want to do is:

 -I have 2 excel files and 1 powerpoint presentation
 -all of the files are in a shared network
 -I linked my excel files to the powerpoint

The problem:

I play the slideshow of the powerpoint and set it to loop on 1 computer to display it on a big LCD at work, I then access the excel files on a separate computer and update it from there, the problem is the slideshow that is playing wont display my changes automatically. I have to manually stop the show and click the (update link) on the slides to have it show the updates I just inputted.

Is there a way so that the slideshow will display my updated data within the show and I wont have to manually stop it and click the update link.

I have found a somewhat similar question here but it was not answered to the point where it will help me advance my question.
