Can we create an Anti-instalock feature to Blind pick normal games?

I usually practice champions I'm learning in Blind pick soloq and about 40% of the games someone calls a role and just instalocks whatever they want in the first 3 seconds of the champ select; Can you implement some kind of timer where you've got to wait like 15s or something before champions can be locked in? I know it doesn't fix the problem completely but it does leave time to debate who got the role in question. Thanks for reading. C:
