How to change clefs?

Hi, I have a piano piece that starts with a left hand pattern beginning up above middle C and continues here for about 16 bars before moving down into the bass. Is there a standard way to notate this? Two treble clefs? Can I force this input in Dorico?

Of course. Invoke the caret at the start of the relevant stave and type Shift-C g Enter. Alternatively use the Clefs section in the right panel of Write mode.

Cool, thanks Leo!
