Placement of new clef within measure

Hi-

When there is a clef change within a piece of music, like this:

    \version "2.24.3"
    \relative c {
       \time 4/4
       \clef "bass"
       a b c d |
       \clef alto e f g a
    }



LilyPond places the new clef at the end of the previous measure. Is 
there any way to have the new clef occur at the beginning of the current 
measure?

Thanks

Peter
