How to use doom build when making small changes?

What happened?

I’m trying to update org-wild-notifier

What did you expect to happen?

run doom build and update the change. Instead it updates every package even though they haven’t changed which takes ages. Is there any way to build only packages that changed?

I’ve noticed that doom build when run two or more times sequentially takes just as long each time. Shouldn’t doom build check for changes,and only build those changes? Compiling realgud takes forever on my laptop!
