@hsiehmh Glad to hear you’ve been enjoying using and developing HLAs! Can you share an example of what kind of messages you wanted to append? Feel free to share a screenshot with an example text you want appended, so we can get a better idea of what you’re working with. Also, I’d love to learn a bit more about your overall workflow and how you use the data table.
We unfortunately don’t provide the ability to control what appears in the tool tip popup while hovering over data table entries. The text in the tool tip simply mirrors the text inside of the data table entry you are hovering over.
If I understood your request properly, it seems you want to customize what the tool tip text displays, is that correct? Right now, any added text would need to be added via a new column entry, or within the same data table box, but this is certainly something we could look into!
