Adjusting patterns

[Karidemus]

Im sure this is addressed somewhere, but sadly I can't find it.

Once I upload a picture to be changed to a pattern, is it possible to adjust the pattern manually? I wanted to clean it up, manually reduce some colours, etc.

Thank you for your time.

The short answer is no.

The long answer is maybe in the future, but it has not a high priority.
