Call rejection list maxes out at 100 numbers on Samsung Galaxy S5 - Can I expand it?

I get a lot of telemarketer calls and use the native call rejection function all the time. Apparently it maxes out around 100 numbers and I've maxed the reject list out. I can't find a way to expand the capacity.... is that possible?

I know there are other call blockers out there but they've all seemed problematic in some way. I've never found one that worked 100%

This is on a non-rooted Samsung S5 running 5.0 and on the Page Plus/Verizon system.
