2. Prerolling subsequences isn´t working.

I´ve been really happy to figure out how to add “preroll” and “postroll” to stuff like alembic caches.
So, if you´re cache starts later in the sequence or ends early, instead of looping back to the initial keyframe, you can set a preroll or postroll and it will hold the current position of the cache.
Unfortunately that doesn´t seem to work with subsequences.
For example I´m often using sequences created by datasmith importer when importing animated objects and for those the preroll doesn´t seem to work properly: Bevore the sequence starts, it will render out the end of the sequence instead.

I think I´ve found a workaround for this: If you simply extend the subsequences range beyond the start/end), it will evaluate properly in the rendering.
Its still just a workaround, as that means you need to offset it in the rootsequence to matche the position it needs to start at.
If you can use straight numbers its not a big deal, but when you have multiple subsequences at odd frame numbers, this can get tricky and confusing very quickly.
