13th Age Character Sheet Issues

Hi there- I just set up a character using the 13th Age sheet and all was smooth until I tried Turn Undead. This spell has multiple targets however when you click the spell it only rolls 1 attack roll, is there a way to change this?  Also I wasn't sure how to macro the damage for my attacks as it only has a WIS-base in the attributes and there isn't an easy sum to get the modifier from this value so I just made a new modifier called WIS-Mod. Can anyone tell me what the proper way to do it is? Thanks

Within the context of the sheet and the way it works, I don't believe there's a way to have a single ability to roll multiple attack rolls. In this particular case, it would be necessary to use the power once per enemy. If I'm wrong on this, I would certainly like to hear how it could work. WIS-Mod is the right way to do this, actually. It's what was used within the pregens used in 13th Age adventures.

WIS-Mod doesn't exist in the attributes tab- I have to create it myself. The correct way to do it, I found out was (WIS-base -10)/2 but when I tried to add in CHA as well the macro went crazy and wouldn't work.  As for the attacking multiple targets- I just used one of the custom slots for extra attack rolls, so instead of labeling it 'hit' or 'effect' or whatever I just chose custom and one the line of text I had 'Target 2: [macro] Target 3: [macro]' etc. It works well enough for now:
