Easily. Create the effect/s, then click the 'file folder' icon in the toolbar, give this new template a name and it will appear as just another icon in the effects list - at the bottom.
To replicate an effect, select all the clips to which it is to apply, then click the FX button on any one of those clips to open the effects box. Create a new effect or go with what's already programmed and click the "REPLACE effect chain in other selected clips" toolbar button - usually the sixth from the left. The effects shown in the configuration window will replace all effects in the selected clips.
To APPEND instead, use the next button to the right.
