Heirarchy Numbers in Assembly

[FLATBED]

Heirarchy numbers? I have generated multiple sub assemblies that can be configured using the equation editor portion of the program. I would like to combine those assemblies to make a larger assembly that can make all of the sub assemblies adjust using the equation editor in the main level. I found that the equations generated in the sub assemblies do not follow them into the larger assembly. I also found that the Hi#'s change on the individual components. Is their a identifier that does not change when loading a sub assembly into a larger assembly? Or is their an option or setting that will maintain the Hi# between assemblies. I can copy the equations from the sub assy's and paste them in the overall assy without much trouble. If I change the prescript on the governing dimensions to match the new assembly prefix it will adjust the dimensions of the sub assembly without much difficulty. However all of the suppress/unsuppress commands do not work because they have the wrong Hi#'s. Ideas??
