[chimerax-users] eachChain option for fitmap?

Hi, Fitmap has on option to fit each model sequentially (eachModel). Would it be possible in a future version to add an "eachChain" option to fit each polymer chain in a mult-chain model independently? This would be useful when quickly fitting oligomeric models to an EM map. Alternatively, is there another quick way to do this? I thought about using perframe, but that only take numerical ranges, not alphabetical Cheers Oli
