OK 
It seems that track cutouts are important in O-scale, so I will consider adding of a dedicated feature for cutting sectional tracks in SCARM track plan and such function may appear in some of the next versions of the program.
Track libraries are created to represent the real products, manufactured by the track producers. So adding of helper flex tracks in libraries where the producers does not provide such may lead to confusion in some users.
Changing of the libraries just to place another flex on the plan may be annoying. To avoid this, just place one dummy flex-track on the drawing plot and copy and paste it each time when a cutout is needed, as Ace do. If you do not want dummy tracks on the plan, you can just copy and paste some ready flex cutout and then reshape it. To reshape flex-track, select it, right click over it and then select “Reshape” from the context menu. Reshaping also works with Toolbox flex-track modeling tool.
