Yup, try something like this -

[macro-blocktollfree]
exten => s,1,GotoIf($["${MACRO_EXTEN:3}" = "800"]?goaway)
exten => s,n,GotoIf($["${MACRO_EXTEN:3}" = "888"]?goaway)
(etc...)
exten => s,n,MacroExit
exten => s,n(goaway),Playback(goaway)

Then, if this will always be your first priority, you can include it 
globally with something like

exten => _NXXNXXXXXX,1,Macro(blocktollfree)

Just make sure all other exten => lines start at priority 2 so you don't 
have a conflict.

HTH,
Trevor
