Yes, in the period we speak.
Is dificult to explain.I will try.
But they were 3 classes of Standard-bearer's , in portuguese "Porta-Bandeira".
There was a "Cadete"-Created in 1757, as form of recruiting noble officials for the Army. While they were not promoted to a full rank officer position were subordinated to Sergeants.
There was a "Porta-Bandeira"- a ensign.
There was a "Cadete Porta-Bandeira"- Rank created in 1797, due to the abolition of Porta-Bandeira (Standard-bearer's) position.This Standard Bearer was between The Ensign and the Cadete.It was not a official.
And there was in the period we speak , the "Alferes" the old "Porta-Bandeira" abolished, that in English could be the 2nd Lieutenant ,Cornet or Ensign.
The new Porta-bandeira was created.I think that in the military organization (1808) the Porta-bandeira was a funtion and not a rank,like the Musket Smith, Band master, etc.
They carried the flags.
As for my email, i should wrote "alferes" -ensign, and not Standard-bearer's( the old name).
Hope i could explain.
Is confusing ..
