Autocomplete - exact match from start of string ?

Hello,
Is there way to only match on strings starting with the first characters input?

For instance, if I have a list as such:
[ 'Tamara','Amy']

when I start to type 'Am', I only want to see "Amy" in the drop down list, not "Tamara".

I feel like this should be an easy configuration option or easy mod, but alas, I could not find it.

Thanks in advance!
