Set a default form backgroundimage in Visual Studio WYSIWYG editor

Question

Context

• Viusal Studio 2019, Windows 11
• .NET 5.0
• Winforms Project

I have a VB.NET application with 3 form backgroundimage depending on working environment (Production, Integration, and Test).

I set this backgroundimage at application start when users choose the working environment and I store the backgroundimage in a public variable ```imgBackgroundFormUsed````

In the form designers, i set the background image for the forms and its controls using this variable, e.g: Me.grpCorpusMetaDatas.BackgroundImage = imgBackgroundFormUsed

Problem

in Visual Studio, WYSIWIG form editor, the background image is set to None and the edition become pretty lame, considering that i set controls forecolor to white

Question

Is there anyway to set some kind of default background image in the Visual Studio WYSIWIG form editor, only for this particular project ? I could set the appropriate backgroundimage when forms load but it would add lots of codes.
