[NXOpen VB] How to remove parameters of a feature/object

Hello!
I'm new to NXOpen Journals but I have almost reached a good progress on my journal.
Let's assume you want to run a journal inside a part.
The main and only goal of my journal is to generate/create a surface which is the result of an extrusion or in certain cases of a Surface generated with a swept feature. That's all.
My script is organized with a section where you toggle the possibility to create a Datum CSYS, choose its layer, then insert many parameters which will create geometric entities (like points, spline, directions, arcs, helix, all needed to generate the surface), choose if you want to show them, choose again a layer where you will find only the support geometry, then choose the work layer where you will find the final Surface (which is the main function of the journal).

So, this is the workflow:

1. Datum (Yes/No) and its layer ---> Done;
2. Geometry and its layer ---> Almost done;
3. Surface (Extrusion on Z direction or made with a swept) ---> Almost done.
4. Starting with a new part (empty), on the Part Navigator I want to see only the Datum CSYS and the Body which represents the Surface. Other entities are without parameters, so they are not listed on the Part Navigator panel.

My question is this one: is there a way to remove parameters of helix, extrusion, swept function?
I would like to have a journal which does not need to "scan" or search for determined object on a layer or certain function listen on a "For Each" loop.
Still today I'm not finding the solution... :(

For example (hiding parameters lines), the following code generates a Swept feature on the Part Navigator. If I manually remove the feature parameters, I obtain a Body on the Part Navigator. I'm trying to get this automatic with the journal.

Dim sweptBuilder As NXOpen.Features.SweptBuilder
Dim nullNXOpen_Features_swept As NXOpen.Features.Swept = Nothing
sweptBuilder = workPart.Features.CreateSweptBuilder(nullNXOpen_Features_swept)
Dim swept_surf As NXOpen.Features.Swept
swept_surf = sweptBuilder.CommitFeature()
sweptBuilder.Destroy()

I hope someone could help me.
Best regards,
