Scenario consist transfer to Preload Quick Drive

[jalsina]

As you know the consists located in the Preload folder appear for any loco in Quick Drive. Also a consist built with the Quick Drive Custom Editor will appear in Quick Drive.
I have also made some consists using RW_Tools to be stored in Preload.

My question:

Does anybody know about using or transferring a consist made in the Build Scenario Editor (and saved as a custom consist when clicking the grey cubes) to a Preload folder for QD usage?
