Bends and Slides

I am greatly enjoying Musescore 4. Thank you for this amazing tool! Currently, I am working on a guitar score and can easily add a full bend to a note, but I have not been able to figure how to add a quarter or a half bend. Similarly, I can add a slur between two single notes but not between, say, two triads to slide from one chord to another a fret up or down. If anyone can instruct me or point me to instructions, I would be most appreciative. Thank you.
