Set Read Ahead Latency Control on Per Game Basis?

I really like the new Read Ahead technology. It really make some old games much more snappy.

However, I haven’t worked out how to save the settings on a per game or even on a per core basis.

It’s getting a little laborious jumping in and out the menu to change the setting when I change from playing, say, Sonic the Hedgehog on the Genesis Plus core to, say, F-Zero on SNES9x.

If it’s not possible just now to set the read ahead per game, is that something that could happen in the future?
