How Do I Delete a Linear Analysis Point from a Block Diagram?

I have a Simulink block diagram and on one of the signal lines I set a linear analysis point: right click -> Linear Analysis Points -> Input Perturbation.

Now I want to delete that input perturbation from the model. How do I do that? The only way I see to do that is to completely delete the block that is the source of the signal, and then reinstantiate the block. Surely there must be a better way to do this.

Go to the Simulink Model, click on the link from where you want to remove the linear analysis point. Let us say that the existing link has an Input Perturbation to it. With the link selected, go to the linearization manager tab, and click on Input Perturbation again. Re-selecting the same selection, removes it.

Choose Model Lineraizer in the APPS tab. Select Edit Model I/Os in the Model I/Os drop down menu. Highlight the signal and click Delete. More info is at https://www.mathworks.com/help/slcontrol/ug/specify-portion-of-model-to-linearize-in-linear-analysis-tool.html

That works. Too bad I have to open that tool just to delete a linearization point. There should be a choice for "None" on the Linearization Analysis Points menu directly in Simulink.

Another option is to use

io = getlinio('mymodel')

to get all of the linear analysis points in the model, then delete the one I don't want

io(3)=[];

and then reset the model

setlinio('mymodel',io);

This approach is also unsatisfactory.

Way simpler option :

With the link selected, go to the linearization manager tab, and click on Input Perturbation again. Re-selecting the same selection, removes it.

That is a way simpler optoin, thanks.
