Input notes among themselves within measure without adding up their duration

Hey there,

I need your help with the following: I bought a sheet and want to transfer it to MuseScore for learning purposes (I already did that more often so meanwhile I am usually able to do so without bigger problems).

As you can see in the attachment, the song is 3/4 and the notes in treble clef are supposed to be played by different finders at the same time (hold the b and play d and f alongside). Which is solved by the pause sign underneath the b note.

How am I able to transfer this in MuseScore? Because: If I place the b note the measure is already "full" and if I want to add the pause or d or f note they are added to the duration so it is not possible to place all the notes exactly like in my sheet (attachment).

Any help appreciated, thanks..
Sarah
