Airport approach ?

When I fly an ILS approach into PAJN Juneau, Alaska from the east on approach to rwy 26 ATC has me fly an approach into Juneau over the mountians, this is very unreallistic, it does the samething with all ai traffic. The normal approach to rwy 26 is to fly up the Lynn Canal Channel then turn left to line up with rwy 26. Is there a program or aftermarket addon to correct approaches, I'm sure this isn't the only airport with this problem.. Any help would be appreciated...

Thanks
