Delete a part from a subassembly in design table

Hello, I often use in my design table the variable ''$ETAT@assemblyname<1> for either resulu or deleted.

Is it  possible to do it with only one part in a sub-assembly without making a configuration and that it does not delete the complete assembly if yes I would like to have the formula to write of the type: design table main assembly:  ''$etat@partname@subassembly<1>' ' r or s

Not to my knowledge.
In fact, I would say that this is not the spirit of the function.
