Lyric Notation

I have been notating choir music in Italian. Some of the syllables are separated by a curved underline indicating that the syllables are to be pronounced as one syllable on a single note. For example the word "l'a-ver-mi a-ma-to" has the symbol between "mi" and "a-ma". Using the symbol table, I have found that I could use the slur symbol but the slur is placed half-way up on the letter rather than below the letters.

Is there a way to place the symbol below the letters?
