Captioning a Sequence with set In and Out Points

One of our producers just captioned his sequence.  He had an In point set at timecode 0:03:53 (start of video was at the In point).  His Out point was at the end of his project.  He captioned it and sent engineering the video and sidecar caption files.

When it was tested, the captions did not show up until 3 minutes and 53 seconds into the video.  Is there a setting in Premiere where the caption timecode can start at 0:00:00 even when an In point further in the timeline is set?

Also some of our producers edit multiple videos in a timeline with In and Out Points.  Can multiple files be captioned at a time?

Thanks
