Balloon enlargening

Hello everybody,

I worked on really big complicated 2D drawing and started adding the balloons with full filled description. I have a layer for it. But how the drawing became big, balloon, text inside, arrow.

I click on balloon, select matching and trying to find our have to change the text size, etc? I know in toolbox setting I can set everything but it doesn't work on existing ones.Is there any possibility to change setting of all 100 items in one step? is there any solution available me?

 

thank you a lo
