Editor layer conversion

Full of questions today!
Just wan't to confirm that it is not possible to select a sequence of source clips in the editor and convert them all to a single composite? Seems each clip becomes a separate composite...
Wanted to just add a few frames at the beginning of an animation without adding another composite track as I need to color correct the whole consistently and it's a bit more complex to duplicate effects and keyframes accross layers
Yes, I know I could go to another tool! Just trying to reduce workflow - So many tools - so many shortcuts - so many layouts - keep trying so Save As from the FX Home pop up!
Making 3ds Max a plugin for Hitfilm would be good!
