Sorry Pepe, you can't. Those tiles are built into DAI's "runtime"

Regarding all these specialized formatting things you ask to do from time to time -- if there's no user-interface object in the design tabs, which are easy to scan, then the only way you can do these things, if even possible, is via javascript injected into the report at runtime via the rules tab, and/or custom CSS. I've done trivial things with both of these. I've seen others write length javascript to customize how the HighCharts render. The High Charts site publishes their .js library and examples of how to use it, but you can't even use that on the dashboard tiles since they are not high charts objects.

I don't use Dynamic AI for pixel-perfect or heavily formatted output. I use it for the information value it provides. A tool like DF Reports is better suited for highly specialized formatting.
