I'm in the process of putting a track together (for GTR2) and have already used the "Append Track" to get the centreline etc. However after trying the track I found that some of the turns were wrong, so I moved the track. Now I've got to move the fastline, centreline and corridors. So my question is this, is there any way to un-append the track so I can get BTB to then re-append it?
