Ability to manage all the labels of the form using a tool similar to "manage multiple fields"

There are a lot of labels that need to be updated this way (upwards of 80 fields) - is there an easy way to copy/paste to duplicate (eg like manage multiple fields) or would i still need to go into each field individually?

I think you are referring to change the text in the label, in the same way as you mange fields using the "manage multiple fields" tool, I think this is not possible, you will need to add the text on each label individually; however, I will escalate this to our developers as a feature request, although we can not provide an ETA about when it could be implemented, you will be notified via this thread.
