Export Captions to VTT via Premiere Pro

We would like the option to export closed captions as .vtt files in Premire Pro, as you can for SRT files for closed captioning. VTT is the only format that can be used for transcripts, which is a requirement for accessibility in addition to closed captioning (SRT). Creating VTT files manaully or with different software is  very time consuming. Would be extremely benefecial if this capability was added to Premiere Pro, as it is availble for SRT export.
