[5e OGL] Global Healing Modifier

Hey, I was wondering if there is a place to add a global healing modifier to all healing spells.  Life Domain clerics get the +2 +spell level bonus to their healing spells, and while I can have it calculate the +spell level by adding a +1 in the higher lvl cast slot, I can't seem to do it to the static +2.  Is there any place I can do this, or any way? Thanks.

You'll want to specify which character sheet you're using.

How can you tell?  I guess it's SRD5?

For Cure Wounds, in the healing section that says 1d8, change it to 1d8+3. And then just make sure in the higher level cast section you have the +1. Add the +3 to all the healing spells of first level in their "damage" section. Add 1 for each higher spell level. Like Prayer of Healing is second level, so add +4 to the main healing dice, and +1 to the higher.

I have it set like this.  When I cast it at level 1, it rolls 1d8+3, but if I do it at level 2, for example, it just rolls 2d8+2, and doesn't add the +2 base from Domain of Life.
