Headache not listed as an allergy symptom

Hi. Im a newer allergy sufferer.
My allergies developed around 30 years old and are sporadic, so this app is extremely useful in pinpointing triggers. At this time, my histamines are too low for bloodwork or patch tests to register my triggers.

Headache is my most common symptom. Can Headache please be added to to symptom tracker? It is a tension-like experience originating in my temples or sinuses.

Id like to be able to track the headaches with the seasons.
Thanks!
