Hello,
What is a product history message ?
Because for my it would be a history message that you attach to an HikaShop products ; and there is no feature in HikaShop for that and no usage of such kind of information.
There are a lot of different kind of custom field and vendor can access/modify the big majority.
So please be much more precise.

By the way, do not send me private message, use the "contact us" form instead.
