Can i connect waste pipes into soil pipe tee on a horizontal run? I

[Illuminate]

Obviously I know the boss parts on a soil pipe tee are there to be cut out to connect waste pipes and I have done this when it is not a horizontal run but i was wondering if i can connect the soil tee horizontally and still connect waste from it? I have attached the part and rotated the inage on the way I am connecting the tee, obviously the toilet connecting down into the top of the tee but can i connect waste to this tee boss on a horizontal run awithout having to drill into the soil pipe ?

No I wouldn't recommend you do that it will almost certainly cause blockage issues .
