Merge Notes With The Same Pitch

The button (Icon) you will find in the Tool bar Tab (Category) <Work>.

Mark the two notes which you want to merge. Then click on the corresponding button. The new note value is the sum of the note values of the highlighted notes.

Also, you can mark the more bars and staves. All the notes with the same pitch found there will be processed with this function! It is very often useful to get the new melodic versions!
