You probably mean automatically like in a batch setting.
Otherwise, one idea, have you tried, in your case, using Replace Feature.
You first make the current feature before the instance. Next create a new pattern over top, but not exactly the same because you will change it later. Make the old instance your current. Then use Replace to replace the feature removing the old. Now change the parameters of the Pattern so it will be the same as before. Will this help or too complex?
