Can I be Notified of Updates to Exports Prior to them Occurring?

Every so often, there will be an adjustment made to the exports maybe a shift in a column, an additional blank column, etc. and our ad hoc reporting is then thrown off by these shifts. Does anyone know of an email list I could be on to be made aware of changes that are coming down the pipeline PRIOR to the change being made so I can have time to adjust formulas, queries, & pivot tables as the changes occur.
