Where is the speech bubble object in premiere? This is insane.

There shoudl be a speech bubble object in Adobe Premiere. Where is it? I don't want to add external speech bubbles as PNG files, because changing width, height and size doesn't produce good results. I need a built-in speech bubble solution for Adobe Premiere. Where is it?

If one doesn't exist, how do I append a triangle image to text? To clarify, let's say I add text to my premiere video, then I give the text a rectangular background.  Now I want to ad a triangle image in the corner of the rectangle. How do I make that image triangle built-in to the text? Not a separate layer in the video editor? 

Basically, anytime I add text, I 'm going to give the text a background; that's built into the text object, then add a little triangle so the speech text can point to characters in the video.

There's a tab for graphis for text, how do I actually add a graphic to it?
