How to prevent IntelliJ IDEA from importing "*"?

(IntelliJ IDEA newbie here; you have been warned).

It seems like after a few imports like

    import a.b.c1;
    import a.b.c2;
    import a.b.c3;
    ...

IDEA decides it knows better than you and changes what you typed to

    import a.b.*;

If that's what I wanted, that's what I would have typed, TYVM.  Is there
any way to disable this (to me) enragingly annoying "feature"??

Thanks in advance!
