Dotted slurs?

Is there any way to get dotted slurs in Notion? Sibelius has got several possible slurs.
I need this between notes that is supposed to be sung on the same vocal and on the same note two times, but to let it sound like a new note. Example:
"Al - le - lu - u - ia"
the "u" is on the same note as "lu" and to avoid this to sound like one note the choir should kind of accentuate the "u". This would normally be written with a dotted slur between "lu and u".
My dash problem worked out btw.
