You can store the subtrack you have selected independently from the track you selected it from. If you do not do this, the track will be lost as soon as you select a new subtrack or as soon as you close the original track. To store a subtrack, proceed as follows:
1. Right click on the graph of the subtrack or on the track. The context menu will open.
2. Select the menu option ‘Save subtrack as’ (using the context menu, you will find this option in the subtrack section).
3. Select the folder where you want to save the subtrack (default value for this option is the tracks folder of Land/Air) and give the subtrack a name.
4. Click on save and the subtrack will be stored in the folder you have chosen and available for use whenever you need it.
