create/edit feat param in assembly

by using proselection i can able to create component/feat parameters in assembly

but when i try to create a parameter instead of selection it will create either part or assembly level parameter.

Is there any option to create or edit Feat_Param in a component level in assembly.

///*****************WHILE USING BELOW CODE IT CREATES CORRECTLY****************************////////////////////

err = ProSelect("component", 1, NULL, NULL, NULL, NULL, &p_sel_array, &p_n_sels);
err = ProSelectionModelitemGet(*p_sel_array, &p_mdlitem);
err = ProParamvalueSet(&new_value, (void*)L"FIND_NUMBER", PRO_PARAM_STRING);
err = ProParameterCreate(&p_mdlitem, L"6", &new_value, &new_param);

instead of selection i need all components list in the assembly

err = ProParamvalueSet(&new_value, (void*)L"FIND_NUMBER", PRO_PARAM_STRING);
err = ProParameterCreate(&p_mdlitem, L"6", &new_value, &new_param);
