Too Many Option Variants Causing Problems In Cs-Cart

Several of my cs-cart store owners use heavy amounts of product options and option variants. They have run into problems with cs-cart when variants go over several hundred on a single product option (global or local). The admin area stops letting them modify option variants when this happens. We have tried increasing max_input_vars, but this doesn't always work. What other PHP settings or MySQL settings do we need to increase inorder to allow the editing of product options that have hundreds of variants? Or what can I change in cs-cart code to help eliminate this bottleneck.

Currently I am forced to use PHPMyAdmin to manually modify product option variants when this happens.
