RGB and CMYK Both values on samples instead conversion (Please solve this problem)

Long time away we have several problems on conversión, both rgb to cmyk or cmyk to rgb. Todays brand needs use multi-channel enviroments. The use of Adobe Library´s made this ecosistem too much efective, but here we aways have the same problem with samples, the conversión works well at 99% of photographys but at only a 10% of color samples, that usually are well defined on corporate colors.

We usually made in-design or illustrator files both to web content or to be printed in hard systems, sometimes change colors samples by hand on all of assets are imposible. Define the output of a sample both in RGB and CMYK will solve most of color problems on  corporate brands. Thank you!
