Hi there
This is very difficult to do in Sibelius. There is nothing that does any part of it automatically.
If you have graphics software that can create the lines fairly easily, it might be best to do that, and import the lines as graphics.
However, getting the size of the graphics right is not straightforward, and manipulating them within Sibelius isn't completely easy.
You may need separate graphics for score and parts, depending on how the layout differs. You will probably need separate copies of (some of) the graphics for the parts. (Use 'Show in Score' for one, and 'Show in Part' for the other.)
There are other options, though not the same visually, that can be done completely within Sibelius.
For me, the most useful of the methods I've tried is to use the straight slide line between notes, with a completely-invisible notehead style, and some adjustments to the start and end position of the lines.
A picture of this approach, showing the score and part versions of the same bar, is attached.
(Incidentally, the straight lines do not affect the performance: players will make smooth transitions between up- and down- glissandi in either case.)
Hope that helps a bit, anyway.
