Custom Project Properties and Conditional Parameter (Redefined)

Hello,

    I've made simple NMake Project that I modify to launch a batch file inside a specific SDK Folder. This batch file use xtensa-elf to built ESP8266 MCU Chip (future, i will support atmel MCU).  I use this tutorial to perform Custom UI. But I've problem with conditional parameter. My Item Group was define like this:

<ItemGroup Label=""><PropertyPageSchema Include="$(ESPBuilderFolder)Template\SchemaItem.props;$(ESPBuilderFolder)Template\Compiler.props"><Context>File</Context></PropertyPageSchema><PropertyPageSchema Include="$(ESPBuilderFolder)Template\MCU_General.props"><Context>Project;General</Context></PropertyPageSchema><PropertyPageSchema Include="$(ESPBuilderFolder)Template\Compiler.props"><Context>Project;Compiler</Context></PropertyPageSchema><PropertyPageSchema Include="$(ESPBuilderFolder)Template\ESPBuilder_General.props"><Context>Project;ESP2</Context></PropertyPageSchema><PropertyPageSchema Include="$(ESPBuilderFolder)Template\ESPBuilder_Flash.props" Condition="'$(ESPBoot)'=='None'"><Context>Project;ESP</Context></PropertyPageSchema><PropertyPageSchema Include="$(ESPBuilderFolder)Template\ESPBuilder_Boot.props" Condition="'$(ESPBoot)'!='None'"><Context>Project;ESP</Context></PropertyPageSchema></ItemGroup>

But I get this Form

I will Get This

The general part is define like this: (ESPBuilder_General.props)

The second and the third part, look part like this: (ESPBuilder_Flash.props & ESPBuilder_Boot.props)

Question:

Does It's possible to configure ProjectShemaDefinition to be merged inside one TAB?

The only way I found it's remerge (ESPBuilder_General.props + ESPBuilder_Flash.props) & (ESPBuilder_General.props + ESPBuilder_Boot.props). But it's create redundant entry and it's a little boring to modify.

Thanks
