Dashboard subscription is capped at 10 columns

When I tried to send dashboard subscription to Slack, the image is capped at 10 columns. I know it is mentioned somewhere in the docs, but is there any way to change the limit? Thanks!

Hi @bentang
That is currently hardcoded, along with several other values, but there's a request to make some of those into variables.

Though, in this specific case, there's some limitations in the size of Slack images, so I doubt that it will be possible to allow a lot more column without being truncated anyway.
