Pathfinder Sheet spell DC question

Is there a way to set a buff or toggled Variable  for the DC's of spells My Ratfolk Cleric has an item increases her caster level and  Save DC's of all her spells by +3 i have found how to increase my CL but am having some brain scratching over the DC's this is an item that could very likely be stolen from her by NPC groups  so i would need an easy way to change that up pretty quickly  and i dont want to have to constantly do some math( lazy player syndrome) every time i cast a spell Thanks in advance peeps

As you've discovered, there isn't a built-in buff for DC on the sheet. You can adjust DC as well as CL per spell from the Misc sub-section of a spell.  This can be tedious if you need to apply a global +3 to DC.  ;-(  I'll add a feature request for the sheet to include a global DC buff and/or change the DC and CL fields on the Misc sub-section into macro-enabled that allow formula and queries.  In the meantime, you can either mentally adjust your DC, modify each spell's DC on the misc sub-section, or maybe add a reminder under Spell Notes ie **+3 DC for magic item**

 Alright, I appreciate it Vince, I was hoping for an answer i could be lazy with, guess its time to enable spell notes now lol   ^,^ As always thanks for the info ^,^
