Export timeline with 24fr handles

Hi,
This is the second question, thanks for your help!
I would like to export the timeline and export new clips that are trimmed from the original raw files into quicktimes with 24+24frame handles for each clip in the process.
What is the best way to do that in Resolve?
And when I receive the graded clips back (each clip will have 24+24frame handles right?), how can I easily swap all clips with the new ones without changing the timeline timing?
the idea is that the graded clips have a bit of handles to allow margins in the online.
