I want to add new parts to the toolbox so that when it is dragged into assembly, we get the option of choosing material and size (like regular toolbox parts).I have tried adding configurations and derived configurations to the parts but they appear as one long list in the properties manager when dragged into the assembly.Moreover its more convenient adding part number and descripton through toolbox setup than adding it in individual configurations.
Thanks for your help.
