How to give the secondary represent as defaut answer without pop up msgbox when I drop the symbol in the visio?

Hello Everyone
When i use dropsymbol VBA to drop symbole, there are many channle input terminal symbol which had been used in the loop drawing, i want to drop the panel drawing for those channel input terminal, when i use the VBA to drop those terminal, it will pop up msg box to select the secondary represent option, how can i use the VBA to give it answer without selecting for every symbol, otherwise it will cause lots of manual action to choose. I want to do automatically. Thanks!
