[Chimera-users] Making a composite residue

Hello, I wonder if it is possible to construct a composite residue from two existing residues in Chimera? What I would like to do is concatenate residues ALA100 (mid chain) and GLY200 (end of chain) to make a composite residue AGL100. Chimera won't let me set the same residue number via the "resrenumber" command. Preferably, the composite residue would have all the atoms listed where ALA100 was in the original pdb. While I realize there are trivial text editor-based workarounds I would like to know if there is a native way.
