You can do this with shortcuts, will that be enough?
You can use “[” and “]” to move a layer based on it’s in-point or out-point. When pressing these keys it will move the layer/pre-comp to the current time.
You can use “Alt + [” or “Alt + ]” to trim the layer/comp to where ever the time indicator is.
So if you want your layers in-point to start at 10seconds you can go to that time click “Alt + [“. Then click the “Home” button on your keyboard which will move the time indicator to the beginning of the comp. Use “[” to now move the layers in-point to the beginning of the comp.
