I'm trying to terminate a huge backfill (all runs) but I didn't find any place to do that. What I can perform is select the runs (up to 25) and then terminate. Is it possible to select all of them not only 25? Are there any configuration to allow that?

Hi Rafael - alas, we don't currently have this capability. Here's an issue where we're tracking it: https://github.com/dagster-io/dagster/issues/8010
