Hello,
In order to provide a "vendor hours" feature, we need to have specifications of the needs ; something which can be flexible enough to be useful for most of HikaMarket users.
Since the requests we had were different each time, we weren't able to think of one solution for them all.
Thus, it would require some specific development for each solution.
Regards,

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