It actually may, I will show you how to test this out with.... ANOTHER MACRO!

(Guys over at auctioneeraddon.com figured this one out, I'm stealing it cause it rocks)
*note: not sure if it needs a semicolon, doubt it since it's just one line though.

Code:
/run DEFAULT_CHAT_FRAME:AddMessage(GetMouseFocus():GetName())
So what this will do, is when you hoover your mouse pointer over a button (or probably any frame in particular) it will give you the name of it. In our case, the Accept Button is named: "StaticPopup1Button1"


From here you have 2 things to figure out.
a) If the name is the same, it will work!
b) If the name is differant, just add a /click to your "All-In-One-Accept" Macro and you should be good to go!

Also, I should mention that SSPVP2 , is a great pvp addon which auto-releases, auto-joins, auto-leaves among other things. And Multiboxerv2 will actually handle the auto-res. If you would prefer to go that route.
