memories used in the stack

When i used a stored memory in the stack on the smartfade ML.... if I chang the memory the stack was updated to the new look. On the colorsource 40av the stack does not update to the new look when the memory is changed. Have others found this same issue? I have not updated to the newiest firm as of yet. Has this been corrected in the update.  I find this a useful way of programing a show where possible... so If I have several cues that will be the same, progam them in a memory... reference them in the stack... and if I need to change the look... change the memory and the cues are all updated automatically that have that memory in them.
