Any Automated Way to Add Deprn Methods / Rate Tables?

There are many seeded table-based depreciation methods that we would like to use for our tax books; however, they have 'Depreciate in Year Retired' checkbox enabled. We cannot update this checkbox on these seeded methods (I believe the deprn methods have been used already for tax books that were obsoleted awhile ago). Thus, it looks like we need to add several new methods - only to get the desired checkbox setting. This would amount to entering over 5000 rates when we factor in all of the rate tables. Is there any automated way to copy existing rate tables or add rate tables high volume?
