One Approve Button for Multiple Approvers

Thanks both for the quick response! I will build the 3 sets of buttons then. Just one last quick confirmation - if in the future we do decide to try out scripting to fulfill the original requirements, will that require a lot of re-work? E.g. will I have to consolidate the 3 sets of fields into one in the future, or just use more advanced scripting but we can still keep the current framework? Wanted to just confirm in case there will be issues with our data later if we need to change the structure in the future.
