Make My-Week useful when a board has more than one people column

Our boards often have more than one People column, for example one column for accountable, another for who needs to take the next action. I would like to be able to determine which People column in a given board is used for the My-week filter. At the moment we can’t use My-Week because it would pull all the tasks where anyone was added to any of the People columns. Here’s an example.

We have an operations board which lists small projects or tasks. There are two people columns, one to show who has overall accountability to get the work done and a second to show who has to do the next peice of work (next steps). In My-week I only want to see tasks where I have been assigned to ‘next steps’.

This could be achieved by including a setting in the People column to include or exclude this column for My-Week.
