Looking at the counties adjacent to Multnomah County (Portland), I'm seeing:
Columbia: Trump +12 in 2016; Trump +10 in 2020
Hood River: Clinton +30 in 2016; Biden +37 in 2020
Clackamas: Clinton +6 in 2016; Biden +11 in 2020
Washington: Clinton +26 in 2016; Biden +35 in 2020
Maybe you are aware of a better proxy for identifying vote totals specifically in the "Portland suburbs" but would be interested to see your evidence of this because I'm coming up blank.
