Caption Tracks in .sqpreset files

We're building UXP panels at a newsroom to automate broadcast → online sequence conversion. 

Issue: Custom sequence presets (.sqpreset) cannot store Caption Tracks. Every new Online sequence requires manual caption track creation (~30sec x 20 items = 10min daily handwork).

Impact: Blocks sequence preset automation despite UXP having createSequenceWithPresetPath() API ready.

Workaround: Save template sequences in projects (many extra steps).

Request: Add Caption Track support to .sqpreset format so automation workflows can create complete sequences with caption tracks included.

Real production workflow blocked. Thanks!
