Linked tables from excel to powerpoint, need to change range, is this possible?

Hi All,

I have a powerpoint presentation that has linked data from excel in tables, basically I just refresh links when I change the numbers in excel to save me the hassle of copying and pasting etc

Unfortunately I need to add an extra column to the table, is there any way I can increased the range of linked cells, so that I dont need to paste the new linked range?

The presentation is very large so I would like to avoid the going through each slide and manually copy and pasting links again

Anyone had this issue before?

Thanks for any help!

any ideas guys?
