Your can write a post [custom command](https://discussion.mcebuddy2x.com/t/mcebuddy-advanced-settings-commands-and-tweaking/30#customcommands) to insert tags. Here’s an example.

Use `PostCustomCommand` to do this at the end of the conversion. See [MCEBuddy - Advanced Settings, Commands and Tweaking](https://discussion.mcebuddy2x.com/t/mcebuddy-advanced-settings-commands-and-tweaking/30#customcommands)
