如何在自定义操作序列中重复使用自定义对话框？

I am using a Basic MSI project in Installshield 2012 Spring. I created a custom dialog in the Dialogs section. This custom dialog is simple. It contains no buttons and 1 line of text that tells the user to Please Wait. I want this to be used in 3 areas of our installer where we have total silence that makes it appear like the installer is doing nothing or crashed.I am using a Basic MSI project in Installshield
