Hi @mcapdevila1612, and welcome to the Forum.
What you are asking is not very easy achievable. Here my try.
[Edit: see the posts below this, for other methods that dont require a 0-line staff or cutaways etc.. Thanks @jesele ]
You need:
- a 0-line instrument (see here)
- an open local time signature for the 0-line staff
- remove the not needed rest in the 0-line staff
- some start and end cutaways,
- hidden noteheads (and just for the dotted note use the notehead color>opacity 0% property, to preserve the dot)
- some manual beam and secondary beam splits
- an elision lyric
- a Pedal line with some added changes to one quarter depressed
- another pedal line for the last chunk
- some manual vertical positioning of the pedal lines
- manual dragging of the o-line staff in engrave mode (to make the whole figure nearer to the piano staff)
- you can then manually hide the 0-line stave in the system where this figure is not needed (and eventually adjust the inter-system gap globally in Layout Options)
The result is not 100% what you show in your screenshot, but is somehow doable (needs a little work).
I hope it can be helpful.
