Keyed ERC links for JCM Morphs - how to make in DS 4.6 or 4.9? (Solved)

Hello! I need again some help in the maze of my Studio's options. This concerns making step-by step JCMs, which require keyed ERC links. I found some short descriptions of this technique within the forum, but they seem to relate to earlier Studios and I canot make them work in DS 4.6 or 4.9. In short, I wanted to make a custom child FBM for Genesis 3 Male based on the clone of Kids 4, and made many JCM morphs for this FBM, but found that JCMs for Left or Right Forearm Bend distort the shape of the elbow when multiplying and so I  need to apply them step-by-step. That means that if I have three sequential Joint Correctives (K4_JCMForearmBendFront60L (Bend = - 60), K4_JCMForearmBendFront90L (Bend = - 90) and K4_JCMForearmBendFront135 (Bend = - 135, full bend), then first JCM should start at 0 to 60,  JCMForearmBendFront90L must work from -60 to -90, and the last one from -100 to -135 degrees. That is the last JCM (Bend Front 135) must not be turned on until bending reaches 100. How to achieve this with the help of Timeline? If I set Bend = -100 at Frame 0 and JCMForearmBendFront135 = 100 at the next frame, how many frames must I put between them - 1 or all 30 frames? And how to ERC freeze just this JCM, not digging in the pile of other keyed properties? When I want to make ERC freeze from keyed range, I see so many properties that I cannot find these particular JCMs. Is there any tutorial about this technique in newer Studios from DS 4.6 and so on?
And the second buggy question - how to hook up MCM morphs for Pose Controls for Genesis 3 Figures, as for Eye Closed or for clenched fists, so that they work automatically? I attempted to link these MCMs for eyes like a regular JCM, and made ERC freeze for Eye Closed Left and Right pose controls, but these links are not saved with MCM morphs. I guess that these Pose Controls on Genesis 3 drive many eyelid bones and so this simpler way do not help me. How to make facial MCMs for Pose Controls in the easiest way?
Thank you in advance for help!

 

Update: I solved this problem now and posted my findings as a short tutorial in Freebies - https://www.daz3d.com/forums/discussion/173151/tutorial-easy-making-of-jcms-and-mcms-in-daz-studio-4-9   I hope it will help to any user with similar JCM problems.
