Subject: Adding handles to image sequences w/o losing existing timing?

I'm in the middle of a nightmare project that I'm supposed to be doing VFX
comps for BEFORE the edit is actually locked.

I transcoded the current R3D selects to DPX sequences (using DaVinci
Resolve w/24 frames of handles), so I dont have to work with the original
R3D files in AE. My usual workflow is to create "source clip comps", by
using the "New Comp from Selection" feature on the selected, imported DPX
sequences. I then use this precomp as the actual "footage" that I work
with, rather than dragging the actual clip itself directly into my comps.

It appears that AE does not use embedded media timecode to reference
discrete frames, so if I add more handles to the originally imported DPX
sequence, the timing of the footage gets borked because it seems AE is just
referencing frames by raw framecount, starting from the physical start of
the media.

In my ideal world, I would like to be able to add handles to an image
sequence, and then have AE automatically detect this and allow me to pull
out more frames on each side of the clip, without disturbing the original
timing of the clip, wherever its being used in my comps.

Any tips to workaround this issue?
