Is there a way to know the previous route location in a `loader`?

react

I have a route like ⁨

/a/:id/:group

/a/:id/:group

⁩ and I have a use case where I want to know whether a loader was called via a link navigation to the same page (⁨

id

id

⁩ stays the same) but a different ⁨

group

group

⁩ or whether the user navigated to a different ⁨

id

id

⁩. I need this info to conditionally refetch some data only when I navigate to a different ⁨

id

id

⁩ but not when I navigate within the same ⁨

id

id

⁩ but between different ⁨

group

group

⁩s.
