Dial Plan

Hi, I am trying to create a dial plan for an IAX2 Inter company route and have a couple of rouge extension I need to avoid

At site 1 the range of possible extension numbers go from 630 to 699… BUT… there is also 606, 605 & 602 on site

At Site 2 the range of possible extensions numbers go from 600 to 629 but I need to avoid 606, 605 & 602

At the moment I have a dial plan on site 1 ( internal range from 630 - 699 + 602, 605 & 606)as
()+|60X
()+|61X
()+|62X

Can you add extensions to avoid as 602, 605 & 606 or do I have to create individual dial plan for 600, 601, 603, 604, 607, 608 & 609 ???

And at Site 2 ( internal range of 600 - 629 )
()+|63X
()+|64X
()+|65X
()+|66X
()+|67X
()+|68X
()+|69X

I presume here I just add the following to included fixed extensions
()+|602
()+|605
()+|606

Seems a bit messy hence the question… Thanks in advance
