Melody question - can you stack notes

A very common lead guitar style is to stack (i.e., two notes are plucked at the same time) e.g., B note over a D note on a G maj chord. Can this be done in the melody section of hookpad. I love using the software to create an archive of the lead sections that I write on guitar. However, i have not figured out if I can stack notes with this software program

If you’ve purchased hookpad you can use multiple voices

I pay a monthly subscription. Any advice on how to stack notes

@finnz79 click on the note staff then in the voice properties panel, click on another voice and add the notes you want

e.g. to have B and D at the same time, input a B in voice 1 and a D in voice 2
