some of us have many files on sale, sometimes we may need to change prices, are there any other ways, except for changing the price of the files one by one? For example, I have only full hd and uhd videos on my portfolio, I want to change all fullhd videos the same and all uhd videos the same prices, so there will be only two pricing on portfolio. Can the Envato Support handle this? or what are your thoughts for changing all prices easily?
