Help Center ticket search filters won't support custom statuses

As we use the custom statuses, and some of them are visible to customers also, we have received quite a lot of feedback from our customers that they would like to be able to see the custom statuses also in their search filters in their own profile in Help Center. Currently they can see the statuses on their tickets, but the search filter only supports the status cathegories. We and our customers would be happy if you could develop this feature. Thanks!
