Ability To Tag People/Accounts in Instagram Post

Tagging other accounts in posts rarely works, especially in LinkedIn and Facebook. After I publish my posts, I have to open them in the native applications and edit them to get the account tags to work properly. Also, I should be able to add posts to a campaign. For example, today I sent a series of posts to promote a news article. Next week, I plan to send "in case you missed it" posts to promote the same article. All of these posts should be part of the same campaign.
