Black and white images options for the users – Product Designer

Dear developers,

We want to buy the plugin (Product Designer), it's just amazing and has a lot of interesting features. We are interested in one feature - we need to have opportunity to make user uploaded images be black and white, but only on selected products by default and not for all the images.

Is it possible somehow ? Or maybe we can open a request for this feature to be added in close future ?

Thank you so much!
