File imports; how to set to ignore tempo etc best practice

When I get jobs come in, when its mix only, I usually have to unravel the ornate :wink: naming of the files, often 1 at a time eg done in protools etc

Then I have to get the Key and bpm as often not provided so thats an issue as even though Im not doing anything, I need the markers/cycles and automation to match etc

There is no production, just pure mixing…but Im wondering how to get the default to ignore all temp info etc?

What are some tips in the workflow that you use?

Cheers

EDIT: Also what is the best way to undo any warp info applied to all tracks?
