Have your summoner spells be the same as the last time you played that role

So, the amount of times we see people either forget smite or a spell or change masteries, etc. can be painful (well at least for me). I was wondering, with the new dynamic queue, why not just have the summoner spells you currently have be the same summoner spells you used last time you played the role. Most of the time, we have the same summoner spells for those roles anyway, i.e. flash and exhaust for supports, flash and smite for jungle, heal and flash for adc, etc. Of course there are some variations (like ignite smite shaco and those variations in the mid lane), but they largely stay the same. And for those that go to normals blind pick right after will play what they most recently had.
