Ym.. ok, so what is solution for a problem like in example? Other example could be a jacket and buttons on it. In most cases, buttons will be different sub-objects. When I'm folding jacket, button could be soak in.
move, scultpt the button afterwards... you only have to klick on it to work on... its impossible to sculpt two objects with "one" stroke... but its working if you make a break... if you need these feature.... use the suggest button in the help menue... autodesk is tracking all these suggs..! help --> suggest a feature
