Suggestion : Repeating rewards after tier no.20 in plant pass

After reaching tier 20 in the plant pass, there's nothing else to claim... we can only wait patiently till the next plant pass for more rewards... But, what if we can still get rewards after reaching tier 20?

For example : every time we collect 1,000 points in the plant pass, we get something infinitely untill the end of the season pass.. what do you guys think?
