How to create a short caption (as \listoffigures entry) with \twopagepicture?

Using the \twopagepicture command like in this example (How to include a
picture over two pages, left part on left side, right on right (for
books)?), is there any chance to create an entry to the List of Figures
which only takes part of a very long figure caption (instead of the
"...very very...long caption" itself; similar to the \caption[]{}
command), such as
....
\twopagepicture{t}{p}{image}*[short caption]*{Other test with
very very very very very very very very very very very
very very very very very very very very very very very
very very very very very very very very very very very
long caption
}
...,
starting form the above-posted example? I am facing this problem in my
thesis for a two-page figure where a long caption is inevitable. A general
option, of course, would be to give the details on the figure in the text
but (a) this does not meet with my supervisor´s approval, and (b) a
statement like "See text for further details" in the figure caption would
also enter the List of Figures which, I think, is not adequate for a LoF
entry. So this option is actually not an option for me. Maybe the answer
is very simple but I have not come across it yet...
Any suggestions are highly appreciated. Thank you very much for your time!
