Formatting in-text citation - choice of 2 styles

Please help me with this one! After convincing my work college to use Endnote I am embarresed to admit that I dont know how to do this.

When referencing we use two formats in-text:

Either :  Evans and Schmalensee, (2005) stated that blah blah blah

and/or: it was found that blah blah blah (Evans and Schmalensee, 2005).

Both need to be available interchangeably and seeing that only one or the other can be used at any one time, my college wants to quit on Endnote out of fustration.

Any ideas on how I can use both styles in the same document?

If not, bye-bye Endnote!
