Two initial capital letters autocorrect in Gmail?

Is it possible to set my Gmail account to autocorrect two initial capital letters? For example, when I type sentences, they frequently look like this:
‘WHat time is the movie? ADditionally, what time should I arrive?’
My Word program has an autocorrect feature for this and I can’t seem to find one in Gmail…
Thanks so much for any solutions to this first-world problem!
