[Chimera-users] Mutation in Chimera

Hi I am learning Chimera and I have gone through soe online tutorials. The tutorials showed how to introduce point mutation by Rotamers command. But it only allows to replace 1 ammino acid residue at a time. I want to insert 4-5 ammino acid residues in a gap of a sequence. Is there any standard procedure, command in Chimera that will let me do this type of residue insertion? This is really crucial for my research work.
