Can you set it so that if 20% of what you're owed is less than 50 points, you get 50 points?

I have a loan with 210 points outstanding, but it looks like for the next weeks I'll be getting it as 42 pts, then 36, then 27, then 21, then 17, then 14, then 11 before I hit the magic number of < 50 points and clear out the loan with the final 44 points. 8 weeks is kind of a drag for 210 points, especially since I've been collecting insurance since early February. :/

I rounded, so my numbers might not be exact. Thanks.
