How to have multiple outlining blocks within an outlining block in WinForms SyntaxEditor (EditControl)?

Platform: WinForms |
Control: EditControl

Outlining block

Consider a scenario where you collapse only a part of the outlining block or the whole of it. For example, let #ifdef - #else - #endif be the collapsible block. When #ifdef is collapsed, the entire text between the #ifdef and #endif has to be collapsed.

But when the #else block is collapsed only the text between the #else and #endif block has to be collapsed. Please refer to the test application attached that illustrates how you could do this. Please refer to the Config_Settings.txt file that contains the relevant Lexem and Split entries used for this purpose.
