Tag people, brands, products, and locations when scheduling Reels/Shorts/TikToks#3161

As a DIY YouTube creator who cross-posts Shorts to YouTube, Instagram, and TikTok through Publer, I need native tagging in the composer — not just hashtags in the caption.

Please add:
1) Instagram: tag people/brands in Reels (@mentions that notify), collaborator tags, product tags, and location tags when scheduling from Publer.
2) TikTok: tag other accounts and add location when scheduling.
3) YouTube Shorts: support tagging another channel / paid promotion / shopping-related tags where the API allows.
4) Per-network controls: set different tags per platform in one multi-post, since brand partners (e.g. @lowes) must be tagged on IG/TikTok for sponsored posts.
5) Preserve tags through schedule → publish so we don’t have to open each native app after Publer posts.

Why it matters: without this, Publer’s free cross-posting still forces a manual pass in Instagram/TikTok for every sponsored Short, which defeats the point of scheduling. Hashtag collections help captions, but they don’t replace people/brand/product tags.
