Hello: I usually add my own lip sync. I clear out what it automatically puts in and then add my own. (I'm picky)

My problem is: when I add my pronunciations, I have to click on one and then the box closes and I have to double-click on the speech line again to add another. This is getting monotonous.

Is there any way I can choose several at a time in the lip sync box? Maybe by pressing "ctrl" or something?

If not, could you put it in a future release?

Thanks.
