Our team has elected to incorporate Spikes into our process as our analysis and previous institutional knowledge suggest that Spikes are more succinct and intended specifically for exploratory purposes, in contrast to Stories. We have tailored our Stories with numerous custom fields that we prefer not to apply to Spikes. However, upon creation, we've noticed that the Spike inherits the same fields as a Story. Could you provide guidance on how to streamline the Spike by eliminating these superfluous fields?
