Datasets in a header

Hi! I am creating a custom Menu bar in my website and I really need to connect two repeaters in it to two different datasets. Whenever I try to connect a repeater to a dataset, it prompts me to create a new one. It connects and work as expected ( I presume it’s sort-of global dataset as it works on all Pages ). Now the question is how do I make a second dataset that will connect to a header?
Thanks in advance,
Jurek

For anyone interested, I figured it out using wix data. Turns out when you reference a database in website code you don’t need datasets to do so.
