Stages available only when another specific stage has been selected in Salesforce

Hi,

In my Opportunity path, I have 2 stages that will only be needed by the user if another previous stage was selected.

For instance, the stages "Pending Document" and "Waiting for Approval" are only needed if the previous stage "Form Requested" was selected. Most of the time, no form is requested and therefore the 2 next stages are not needed.

I would like these 2 stages to appear only when the previous one ("Form Requested") is selected.

Is there a way to make stages appear only when the previous stage has been set as "current stage"?

Thanks.
