Can you mod the map itself?

[phoenix]

Quick question, to which (since I haven't seen any modded maps) I guess the answer is no - but just to check. In PB Kursk, can I change the map itself, to improve it? For example, to double the distance between Gertsovka and the rail station (which is roughly half the distance it should be) by ironing out that odd kink in the line which shouldn't be there (indeed, generally, I wonder whether it would be possible to straighten out many sections of rail line which - as most railways do - simply ran straight in real life - the section from Komsomolets SF  to Oktiabrski SF springs to mind as a section that ran dead straight but which, for some reason, jags all over in the game map). So, I would like to go into a map editor, go over the entire map and straighten out bits of rail line, put in balkas that have been missed etc. Is that possible?

Cheers,

Peter
