Substituting players on a "green" injury..

Does anyone else think the game needs to recognise that when a player is carrying a knock and has a "green cross" against him you're substituting him for this reason, rather than for tactical reasons. I suppose it's not a big deal, but it does annoy me if, say, I have a player on two goals and he's carrying a knock and I take him off and then in the press conference I get asked if I've cheesed him off by removing him before he'd backed a hat-trick. I can't explain that I took him off due to his knock. Even without that happening, I'd still prefer the game to realise I'm making a substitution for the player's welfare rather than for tactical reasons.

Haven't experienced this in a press conference, but if I got this question, I would definitely want to be able to answer like that.
