I need to send differentform submissions to two to three different thank-you URLs (for Meta/Google pixels) depending on which suburb a user selects in a form. I have ~400 suburbs split into two categories (A and B, based on business value).

Current challenges:

• Form Rules only allow 20 values per rule condition, which need to be added individually and makes setup extremely tedious for large lists.

• Suburbs must be entered individually — comma-separated values don’t work.

• Rules are case-sensitive, so “BALWYN” will trigger the rule, but “balwyn” or “Balwyn” will not.

Desired behaviour:

• Forced case for the field input to all caps
  or 

• Case-insensitive matching for text field rules.

Question:
Is there an updated method, workaround, or feature that allows bulk handling of these values without having to create hundreds of individual values?
