When my client sends me a color that comes in percentages of CMYK and I need to create a substitute color, why am I not able to post the desired percentage as the name and then let Fiery come closest? What I mean is that I can create a Spot color, call it what I need to since the client has named it that way (Pantone Cool Gray 4 lighter) but when the same need is there for a substitute color I can't name it as I need nor enter a value exactly as I need...only in 0.5% increments.
