Hi Alex,
Good question! Yes, you can, and you definitly don't need a separate post.
Before you schedule it: in Instant Post, at step 5 (Text and place), write the caption once, then turn on Different caption per account and write the new text only in the TikTok row. Leave the Instagram and Facebook rows empty and they keep the main caption.
If the post is already scheduled: on a scheduled post you can change the time, but not the caption. The quickest way:
- Go to Social Studio › Your posts › Scheduled and press Duplicate on that post. It opens with the same photos, accounts and captions.
- Turn on Different caption per account, change the TikTok row, and schedule it for the same time.
- Back in Scheduled, press Cancel › Cancel the post on the old one, so it dosen't go out twice.
Best regards,
Alice
