Retaining start timecode when stitching spanned clips together

Hello!

I'm currently using Encoder to export MP4s with BITC and clip name for transcribing purposes.

The interviews are being shot on a C300 camera in .MXF format, so the clips are composed of multiple spanned .MXFs every 5 minutes or so.

When I highlight the .MXFs that make up a single clip (and therefore have unbroken timecodes) and stitch them together, I notice that all the start TC is 00:00:00:00.

I've been manually typing in the new TC, but is there a way to retain the start TC of the first clip to avoid this step and inevitable human error in hand-typing the timecode?

Thank you!
