We need a custom field where we can store the conversation history through "Append to the end" custom field step. currently custom fields are limited up to 2800 characters so it would be great to extend this limit to 30k or 50k characters.

Use case: we could use this to store the whole conversation (which can be used as a long term memory for open AI)

So you can simply say in your prompt. here's the conversation history with this customer: {{conversation_history}}

Instead of enabling "Remember this conversation" which will result in max token limit error"
