When switching Checker, it can be used directly after the first subsequent switching and compilation.

Is there an existing issue for this?

• I have searched the existing issues

Is this feature provided in the master branch?

• I have checked the changelog

The problem you are facing

Each time I switch to one of parts of the built-in compiler, it takes 20 seconds or so to compile the Checker.

Describe the feature you'd like

There is no need to compile the built-in evaluator to switch to use, or the custom evaluator is automatically saved to the program checker directory after the first compilation, and you can directly switch to use it next time.

Describe alternatives you've considered
