We would love this functionality! There are an immeasurable amount of custom fields we use in each of our projects, and it's difficult to apply QOL fixes for each without this.

It's possible to limit custom fields to appear only in certain actions. To do this, first, construct an action card template that includes the custom fields. Then, this template can be applied to any actions in which you want the custom fields to be visible.

If you only want to add a specific selection of custom fields to few actions, it would be slightly more convenient perhaps to be able to select custom fields from a list for a given action.

this is very imperative to manage a project effectively
