It's not that easy.. Since a lot of the users said that one of the big advantages of Construct 2 is the affordable price tag. I say, that while I really want to see this feature in C2, Scirra warned us that we shouldn't expect many new features for C2.
IMO: I also love that C2 is not a subscription based software. I believe in one time payments and if Scirra is to raise the price tag, I'd rather pay more for Construct 3 one-time and use it whenever I want, then to pay for it monthly.
