Hi @Amy_Ord, thanks for reaching out!
That workaround is very good, thanks for sharing @Stephanie_Oberg.
We currently don’t have immediate plans to launch a similar feature but I’ve gone ahead and sent your request internally so it can be consider for future updates. I’d also recommend you to upvote for this feature here: Custom Fields: increase max number of drop-down options? . We’ll circle back on the product feedback thread when we have news about the feature.
I hope this helps! Let us know if you have any follow up questions.
