Is there a way to store a value on initial load only?

For example, I want to load a

booking

booking

using

useQuery

useQuery

and then only one the first load for that query, I want to set a local variable (

notes

notes

). So then the booking loads, I can store the notes and then because the save is debounced, I need to keep that notes variables separate.
