Piobaireachd Movements

Piobaireachd is an old form of bagpipe music that has it's own set of embellishments. I'm currently typing in a piobaireachd and I am not finding some of the embellishments needed in the bagpipe palette.
Right now I need a cadence to E and a cadence to C and a rodin.

Cadence to E:

Cadence to C:

rodin:

Is there a way to create embellishments on my own or do you(developers) have to add them to the bagpipe palette?
Thanks
