Amino acid structure expand

I work in a peptide lab so the accessibility to type out 'Fmoc-Cys(Trt)-OH' and 'expand structure' or 'convert name to structure' has been very helpful (picture 1). However, I've noticed that users cannot draw out orthogonally protected dipeptpides via this same function. For example if we type 'Fmoc-Cys(Trt)-Gly-OH', ChemDraw does not recognise the shorthand keys (picture 2). ChemDraw can draw out the orthogonally unprotected dipeptides i.e 'Fmoc-Cys-Gly-OH' (picture 3).
