Hi Benetta,
I am fairly certain this is not on the radar anytime soon, but I would be curious to better understand why your users request this functionality so much? The status options that you are currently able to select should cover any work that a user is assigned to. This article contains detailed information on the filters that can be selected currently.
If you feel adding custom statuses to the Home Work List filter would greatly improve your users ability to work within our platform, I would encourage you to submit it to the Innovation Lab.
Best,
Hannah
