Improvment (small message field)

Hello developers,
maybe there is the possibility of a small message field for each work of art to share individual information e.g. that there is more than 1/1 of a work.
There is somehow work that does not show the real number of mines because they have been mined on other platforms.
The information should only be visible on the respective collector’s portfolio without taking it with you when selling …

Thank you that would be great
