Answer is YES! you can customize your own dialog which is used to show the prerequisites list. And implement the script function which controls this dialog. Then in the setup.rul, add code to call the dialog if your code has detected that some prerequisites were missing.
😞 I did this in installscript project, don't know how to do it in basic msi project either... Eager to know how to do it too.
BTW, an alternative is to use C++ library which create the wizard page, and use custom action to call it. The problem is the dialog theme is not same as IS provide.
