It's possible to add a property or method for disable or change focused from excel？

[SKYC829]

this isn't an ExcelDNA's Error, I've only encountered it in daily use.
so this Discussions are just to see if it's necessary to add a feature

1. popup a 'none-modal window' by use ribbon command button or some way and excel also have a active sheet/ active cell in same time
2. the 'none-modal window' have some form-control for record user input. (e.g: textbox in wpf)
3. when user pressed some keys, key's value was record in excel active cell not in textbox (even if the textbox was focused at first)

The most obvious effect is The TransitionMenuKey command of Excel(Ver 2016/2019) is triggered when user enter a '/' symbol in the textbox. this will cause the popup window to be unable to accept most input unless the window is modal window 😢
