Adding Exit Button for Custom Environment

[thomas.fullerD3PYA]

Is there a way, using the Inventor API, to create a contextual Exit Tab (see the attached image)? 
this is similar to this question a while back (Here), which works only when using the environment in parallel. 

From what I can tell, the "Exit" panel is actually a RibbonTab, but I'm not entirely sure how this is displayed within all the Tabs in the Ribbon.

I currently have a hacky solution where I use the contextual "Return" tab, hide the standard return panel ("return", "return to parent" ect.) and show my panel instead, but I'm wondering;  is there a proper way of doing this?

I want this Environment to launch when the user drills down into a part within an assembly, without having to go to the environments tab.

Could you please try to explain a bit better for me what you try to do?
Maybe some screenshots and steps included.
Thanks in advance,

Here is what I am trying to achieve (similar to Tube & Pipe Routing)

1. User Presses custom "Create Route" button. :white_heavy_check_mark:
2. Inventor creates new part to host a 3dSketch, and adds to the current assembly :white_heavy_check_mark:
3. Upon this new part becoming the ActiveEditDocument, Begin the edit on the sketch instead (I don't want the user to be able to edit anything in the part document, other than the Sketch3d) :white_heavy_check_mark:
4. When edit has begun on the sketch, I want to set the environment to a custom one, based off the sketch3d environment, which includes an extra contextual tab and an including an exit tab/button. :stop_sign:

I've managed to do all but the last step, whenever I try and set the current environment when the ActiveEditObject is not a document, I get errors.

What I've done to get around this is:

• Add another button to the Sketch3D Enviroment's exit tab, but make it not visible
• During step 2, assign a DocuemtnInterest to the PartDocument, so I can identify during EnvironmentChange event
• On step 3, set the current environment to my custom one (this correctly sets the ExitDisplayName), then proceed to edit sketch 
• When EnvironmentChange event fires (when switching to the sketch), check the document interests, if it does contain my previously created one, make my custom contextual tab visible and change the visibility of my exit button, so that it is the only one in the exit tab.

As you can see there is a lot of faf, so I'm wondering a couple of things:
Is it possible to start a parallel environment without user interaction (that may solve this)?
Is it possible to build an environment with its own Exit Tab? like the tube and pipe environments
