Thanks for the comments. The "retain_order" setting solves the problem with cartoons and ribbons, but there is still a small problem with selection of these residues. "select resi 1P-5P" still gives me both 1-5 and 1P-5P. However, "select resi 1P+2P+3P+4P+5P" gives me what I want.
I don't really want to change the chain ID in the PDB file. It makes sort of sense in the case of a propeptide (although it is covalently linked to the mature protein, so it is really only one chain), but many PDB files have insertions which are numbered with "A"s and "B"s after the residue number, and in those cases it really doesn't make sense to change the chain ID. For an example, see 1cgh below.
