Working with 1.3x anamorphic raw files in Fusion 8.0

Hi guys, sorry if this is a dumb Q - first time using fusion....
How do you use RAW footage that was filmed in 1920x1080 but has a squeeze of 1.3x (from an anamorphic adaptor) - I know in resolve there is a clip attribute to unsqueeze it but can you do the same clip options in fusion?
If not, does that mean I just have to render the clips out from resolve first?
If so which format should I use to maintain the best grade? / do I grade before or after the comp? or do I grade in fusion? EXR format in the correct ratio with the black bars? or without the black bars?
Any help is appreciated! thanks
