Previous employment - same company different roles

[pmh]

Hello,

Hope everyone is doing well.

The DS160 asks a question about current occupation and respective dates and job duties.

I have worked in the same company for over 10+ years but the job duties did change from what I was doing when I joined my company.

I was thinking of 1) adding my previous role in the same company with different job duties as previous employment. Is this the right way of providing this information? Or 2) previous employment is to be filled only when you work in different company before.

My worry with 1# is that they misunderstand that there was a gap between different roles when there was none.
My worry with 2# i.e. filling all my experience in the same company as current occupation but job duties over the span of 10+ years do not align and hence seems incorrect and not the right way to fill this.

Any pointers will be helpful to best represent work occupation fields.

Thanks,
Pradnya
