I'm writing my Ph.D. manuscript, and I would like to add subtitles to the list of figures for each part of the document.
I am using \listoffigures and no specific package such as tof at the moment, and the result is this:
It is exactly how I desire (number of the chapter and then of the figure), but I would like to add subtitles indicating "Part I", "Part II", etc., otherwise some figures have the same number without any indication of the part they belong to.
I tried to use \counterwithin{figure}{part}, but I didn't like the aesthetics (something like I1, I2, ... II1, II2, ...).
Is there an easy way to fix this?

titlesecortocloft. Currently it is also not clear, why the numbers of the figures are repeated. So you should at least add a minimal working example, of what you've already tried. – cabohah Oct 02 '23 at 10:19
