When I cross-post the same content to LinkedIn and X, the platforms have totally different norms: LinkedIn wants longer-form storytelling with line breaks and personal/company tagging, X wants a punchier hook and different hashtags. Today, cross-posting in SMM means the same copy goes to both, so I either post a LinkedIn-shaped post on X (looks awkward) or X-shaped post on LinkedIn (too short, no formatting).
Let me cross-post once, then click into each platform's tab to edit the copy and media independently for that platform - while keeping it as a single linked post on the calendar with one scheduled time.
Reference how Ordinal does it (https://docs.tryordinal.com/posts/cross-posting):
  • When cross-post channels are added, content syncs across from the original channel automatically.
  • Each platform gets its own tab at the top of the editor. Click a tab to see the live preview, edit copy, add/remove/reorder media, and see character count and limits for that platform.
  • When you edit one tab, that platform's content diverges from the others. A sync indicator shows which platforms have diverged.
  • A Sync button in the cross-post bar lets you merge changes back. You pick a source channel, pick destination channels, then choose what to sync: Copy (text only), Assets (images/videos only), or both. Sync overwrites destination content. Assets that aren't supported on a destination platform are skipped (e.g. PDFs only work on LinkedIn).
  • All platform versions publish together at one scheduled time and show as one calendar item with multiple platform icons.
Concrete use case for me: I draft once on LinkedIn (full storytelling, tag a company page, link in first comment). Click Cross-Post → X. Switch to the X tab, shorten the hook to fit 280 chars, swap the company tag for the X @handle, drop the link in the body since X doesn't penalize it the way LinkedIn does. If I later improve the LinkedIn copy, I press Sync → source LinkedIn → destination X → Copy only, then re-edit the X version. One post, one scheduled time, two optimized versions.
