Auto-size HVAC from Detailed Mode

Hello everyone. I'm working on a baseline 2-story residential model
using PTAC's for LEED. I'm having problems complying with the unmet
hours in several locations. I have commercial cooking equipment and
laundry machines as my only large loads. I have entered my calculated
heating and cooling capacities and my calculated CFM for each space into
detailed mode. To help with my unmet hours, I bumped my sizing ratio up
to 1.25 and set my throttling range at 6. Still high unmet hours. I
was wondering if there is a way to switch heating and cooling capacities
back to auto-size from detailed mode or do I just have to bump my
capacities up until they cover my hours?
