How do i update multiple links in power point

I have a multiple slide presentation in power point that has each slide showing a graph that is produced in excel. I have linked this graph to my power point slides with no problem but,
When i open the power point presentation it askes to “update” links which is what i wish it to do and this is repeated for each and every slide link.
Seems there should be a way to update All the links for every slide with one click of the mouse. This takes a lot of time when the presentation is large.
So what am i missing?
Any help appreciated.
thank you
