Filter values of a status from another board

Hi !

I would like to link 2 status column.

Say you have a column A for the activity type (Projects, Trainings, etc) and a colum B for the activity (Projects 1, 2, 3, training in topic aa, bb, cc).
It would be great that once the status A is choosen, only the status related in column B appear.
For example, if I choose Projects in column A, I have only in column B a projects list.

And if I have a board with all the projects and the businesses they’re related to, would it be possible to use it in the other boards for those status columns ?
IT would have only their projects, Marketing, also, etc.
