catching up depreciation



I have multiple fixed assets that were setup with 7 year useful life on 04/30/2017.  We caught these this month and realized this group of assets should have had a five year useful life - and therefore already fully depreciated.  What changes should I make to the Depreciation Method and Estimated Life to get Sage to depreciate the remaining NBV for depreciation all in this next Current Period?

They are currently setup as Depreciation Method SF.

Thank you in advance!
