Inputting chords but without ties

hello i want to put a whole note and a quarter note in the same measure but without the whole note changing into many notes tied together. I just want to see a whole note on beat one then the quarter note on beat two

so not like the picture

You need to use multiple voices, so that the whole note is in a down-stem voice, and the quarter note is in an up-stem voice. Check out this video:
