Using Character Sheet Modifiers to Track Cover Bonus

Hey all,  Question about the bonuses of Cover - I know there is the Global AC Modifiers checkbox to add +2 and +5 to AC when in cover, but is there also a checkbox to add the +2 and +5 to the DexSave? I tried the Global Saving Throw box, but that only allowed me to enter something like Bless (which has a dice roll involved). What's the easiest way to add the +DexSave?  Using the DnD 5E OGL standard character sheets.
