Treble Staff MIDI Piano Import

[bilo20]

I have a MIDI piano track that is entirely on one treble staff.
How do I import it into Dorico to a piano grand staff?
And, how do I change its key signature to enharmonically “respell” the notes without transposing them intervalically?

Windows 11 Pro, latest version of D6.

IIRC if your target instrument is set to Piano, then Dorico will split the track (but I may have misremebered).

Dorico key signatures do not transpose, they only respell enharmonically.

I tried to Import to piano but it all stayed on treble staff with many leger lines beneath.
