Connect time tracking + budget plan - functions

Hi

Is it possible to calculate the budget based on the time tracked?

So the budget plan needs to extract the data from the task board from the time tracking.

I saw that you can use functions but does anyone know whether it is possible to have functions between two different boards please?

Regards,
Rik

I made a good start I found in the help section the formulas now I only need to figure out how to collect data from a different board and update it…
