Is it possible to dynamically change the value of a hidden control variable ?

Is it possible to dynamically change the value of a hidden control variable, specifically with other controls on the same dashboard?

My scenario, is that a lot of the templates for Analytics that utilize Project_ID and to change that across all of the different metrics on the Sprint Overview would take some time. I need to add an additional criteria that can narrow down the project/sprint even more - like the Board_ID. 

So, is it possible to use the dropdown for PROJECT_ID, where i can select a Project and it updates the Hidden Variable Control on the same dashboard with the Board_ID that I can then use with other charts on the dashboard?

In Jira Cloud Analytics, hidden control variables are static by design and can’t be dynamically updated based on user interaction with another control on the same dashboard. Each control—like a dropdown or date picker—acts independently, and hidden controls are evaluated only when the dashboard loads or when filters are explicitly changed by the viewer. There’s no native linkage mechanism that lets a visible control (for example, a Project_ID dropdown) directly modify the value of a hidden variable such as Board_ID mid-session.
