SAPUI5 - using a wizard with a splitter

[#1]

Hi everyone.

I'm trying to customize the standard sap.m.wizard

I need to move the first step of the wizard to the left side of the splitter screen, and place 2-n steps on the right side of the splitter screen, while the wizard's header with the step icons should be the full width of the screen, and the splitter's split screen should be below the wizard's header.

As far as I understand, I have a conflict of aggregations of controlls in this case, and the only way out that I have found so far is to use two wizards for two parts of the splitter.

below I attach a code how I use two wizards and everything works.

<NavContainer id="navContainer" class="sapUiSizeCompact">
  <pages>
    <Page title="Creation of Business Partner" id="contentWizardPage>
      <content>
        <l:Splitter id="createSplitter" height="100%" width="100%">
	  <Wizard showNextButton="false" id="createBpWizardStaticLeft">
	    <layoutData>
	      <l:SplitterLayoutData size="30%"/>
	    </layoutData>
	    <WizardStep title="Main Info" id="mainInfoStep"/>
	  </Wizard>
	  <Wizard id="createBpWizard complete="wizardCompletedHandler">
	    <layoutData>
	      <l:SplitterLayoutData size="70%">
	    </layoutData>
	    <WizardStep validated="false" id="addressInfo"/>
          </Wizard>
	</l:Splitter>
      </content>
    </Page>
  </pages>
</NavContainer>

please tell me if it is possible to somehow manage with one splitter and use it flexibly?

Any input, suggestions or remarks are more than welcome!

Thanks in advance!

BR,

Alexey.
