I want to have 2 columns for 3 screens and 3 columns for 6 screens

I’m having trouble with the number of columns in tile mode.
I want to have 2 columns for 3 screens and 3 columns for 6 screens.
However, changing the value of “TILE_VIEW_MAX_COLUMNS” in “interface_config.js” does not fulfill my wishes.
Is there a good solution?

You could change it dynamically with the iframe API, but we don’t have an out of the box solution for this.

I am very grateful for your feedback.
I have confirmed the technology of iframe API, but it seems to be difficult to realize.
Thank you.
