Fixing Authors Names


I’ve currently got a fairly large Endnote Library, and I have noticed that sometimes when I am inserting references into a paper I am writing the same author will be referenced as (for example) Scott, D.A or Scott, Daniel. I’ve worked out that when I downloaded the references off the various databases, the names would come down in different ways which has caused Endnote to think that they are different people. 

My question is, do I have to go through every reference and fix it manually, or is that a search and replace command that can help me find every Scott, D. A and replace it with Scott, Daniel. 

I’m currently working with Endnote X5 for Mac. 

Thanks heaps for your help.

(at least for windows, no idea if it is different for mac)

Thank you
