How to deal with model updates

Hi all,

I work at a PF bank (just lending) and generally as part of the job we have to transform the models we receive from the clients to our own template and run sensitivities and outputs. However, when a client sends multiple versions of a model within a short period of time, it's hard to copy over the sensitivities and outputs tab from model to model and spot check if everything is still running correctly. This is usually fine if the model doesn't have structural changes (no row additions), but often that isn't the case. 

Was just curious if there's an easier way to do this (like having a separate excel spreadsheet to link to the current model) or if I just have to suck it up and update each time.
