Coding AC and HP to scale with level

Hello!  I am playing a Divine Soul Sorcerer in my 5e game, and he is taking the Summon Celestial Spirit from the UA new spells.  I'm building a character sheet for the spirit, and the way it works is the AC is 11 + Spell Level and the Max HP is spirit's CON + my spell modifier + 10 times the spell level.   So my question is, is there a way to code the AC and Max HP to automatically update based on the level?  I figured I could just change the character level on the sheet to be reflect the spell level, unless there is a better way of doing that!  Thanks!

Unless you GM has API available in the game, there's no way to write Attributes. You could create a macro that spits out the numbers, but you'd have to input them manually. Do you already have a spell entry set up on the sheet? You can re-use the Spell Level Query from casting the spell to calculate the Attributes and throw them into the spell description field. But again, you have to enter them manually - there's no way around that without API.
