Click and Drag Word Extensions

WORD EXTENSIONS

I could really use an option to select and stretch a word extension.  

There is an option while adding lyrics to type a word and then type an underscore, but this adds only a very short line at the end of the word.  This is inadequate.  

(At present, I use the Lines menu, with a lot of tedious steps:  select a note or measure; paste a line; the line ends up above the staff or on top of notes, dynamics, or lyrics, so I can't select the boxes on the ends of the line to move them; delete the line; paste a line again; drag each end of the line to where I need it; keep messing with it; end up with a horizontal line that slants a little up or down - not a good look.  One piece of music with a vocal line will need multiple extensions on every page.  It would be quicker to print the music, then get a pen and a ruler and draw the lines in by hand - but that defeats the purpose of having a music transcription program.)

How about a feature that allows me to type in a word extension while adding lyrics, and afterward select the extension line and drag it out to the length I want?  It would be great if it had three options/features:  (1) select the entire line and move it anywhere; (2) select either end of the line and drag it left or right, to lengthen or shorten the line; (3) keep the line locked into horizontal position while lengthening or shortening, able to move left and right but not up and down, so the line stays straight.  

Thank you for considering this!
