[Tex/LaTex] list of figures numbering

numberingreport

I'm looking to include the "part" number in the list of figures numbering.

Here is what my List of Figures looks like now:

enter image description here

I wish instead that each element would show

I.1.1 Caption for Figure 1.1 Part I Chapter 1
I.1.2 etc...
I.2.1 etc...
I.2.2 etc...
II.1.1 etc...
II.1.2 etc...
II.2.1 etc...
II.2.2 etc...

This, of course, if part of a much larger document. I've include all of my preamble with a MWE:

Edit Simpler version

It's easier than anticipated ;-)

Use the \DeclareCaptionListFormat command to define a new LoF figure entry style, say *partfigureand\captionsetup` to active this style 

\DeclareCaptionListFormat{partfigure}{\thepart.\thefigure}
\captionsetup{listformat=partfigure}

No tocloft is used in here
