How do I build only the EJS files I have changed while running the server from the --serve command?

[HIROSUMAN]

Is it possible to re-build only the EJS files that have changed?

While developing locally, I am having trouble with Browser-sync reload time getting longer the more files I have to build with EJS.

Modified EJS file. For example, while running watch mode, I expect to build only the EJS that detects changes, but in reality all EJS files are built.

Also, I cannot figure out how to use --incremental mode by checking the documentation page.

Is this something that can be used in conjunction with --serve or --watch execution?

npm scripts when development

"watch:ejs": "eleventy --serve --incremental"

example

|
|-/src
|     ┗hoge.ejs  // ← changed in --serve or --watch mode
|     ┗fuga.ejs
|     ┗piyo.ejs
|
|-/dest
|    ┗hoge.html
|    ┗fuga.html
|    ┗piyo.html
|

after build

In Console Message

[11ty] File changed: ***hoge.ejs
[11ty] Writing ****hoge.html from ****hoge.ejs
[11ty] Writing ****piyo.html from ****piyo.ejs
[11ty] Writing ****fuga.html from ****fuga.ejs

Expected Execution Result
