This is why you would either have a "support" rota in a team or a dedicated resource for such queries. Interruptions are annoying , but they are much easier to bear if it's just a week in a month. Of course it's not perfect due to the lack of telepathy, exchanging knowledge is not immediate but such rota will help facilitate sharing inside the team as well. I've seen teams that did that, been a part of one for some time and it was really good compared to standard workflow (whoever is closest or nicest is being interrupted).
