inputting two glissandi between two 'double stop' chords

I want to input glissandi on a violin part, from a chord of C (upper note) & E below, sliding down to B (upper note) & D below. I want to input one glissando going from each pair of notes (in the lower and in the upper pair) so two in total. Inputting glissando from C to to B not a problem, as normal. But when I input second glissando from E, expecting it to connect to D, the glissando instead connects upward to B, the destination of the first glissando I inputted. This is all while inputting one voice, not multiple voices.

Is there a way to input two glissandi to two different notes simultaneously in one voice, or do I need to engage multiple voices for the notes in question?
