Is there any protocol to create peptide structures from sequences automatically?

Is there any protocol to create peptide structures from sequences automatically?

The results of followed protocol can only show the atom name, but it can not show the chain name and AA name like a protein or a peptides in the hierarchy windows of Discovery Studio.

So is there any way to change the display style of molecule to the display style of peptide format in hierarchy windows of Discovery Studio (some things like PDB format)?
