In Simulink, how to substitute the default configuration set, not adding a new one??

Here I just list corresponding code sections:

hCs = getActiveConfigSet(gcs);
hCs_1 = hCs.copy;
attachConfigSet(gcs,hCs_1,true);
setActiveConfigSet(gcs,hCs_1.Name);

After running, There are two ConfigSets in the Model Explorer. Every time I run this code, the number of ConfigSet plus one. Although it will work correctly, but it potentially increase the model size. So I need to substitute not add a new ConfigSet, or a method that I can eliminate redundant Configs using command line.

To replace config set: 1. attach new one 2. set it active 3. detach old one

hCs = getActiveConfigSet(gcs);
hCs_1 = hCs.copy;
attachConfigSet(gcs,hCs_1,true);
setActiveConfigSet(gcs,hCs_1.Name);
detachConfigSet(gcs,hCs.Name);
