Append content at the end of a Content Control

Hello, I want to append / edit content inside an existing content control.
Currently, I’ve been using the InsertAndReplaceContentControls - ONLYOFFICE Api Documentation method for replacing content inside content controls. However, I’m unable to find a way to add content at the end of content controls.
For example:
Before:


What I want to happen:

InsertAndReplaceContentControls will completely overwrite the “description” content control. This makes it unsuitable for this task.
What I came up with was to use the MoveCursorToContentControl to position the cursor and the end of the content control and afterwards call AddContentControl.

This works but it seems incredibly hacky. Any suggestions?

Hello @fr3fou
Probably there’s another way to achieve this result. Please take a look at these methods:
https://api.onlyoffice.com/docs/office-api/usage-api/text-document-api/apiblocklvlsdt/addelement/
https://api.onlyoffice.com/docs/office-api/usage-api/text-document-api/apiblocklvlsdt/push/

This way you should be able to add a text or new content control at the end of the current one.
If I misunderstood the situation, please clarify it.
