Query on Transferring Custom Fields from Ideas to Proposals in SCM Innovation Management

Hello everyone, I hope you're doing well! I am implementing the SCM: Innovation Management module and have a scenario where I need to transfer custom fields created in Application Composer from the Ideas module to the Proposals module. The goal is to link this information so that the values are automatically carried over.

For instance, a field called "Score," which is automatically calculated in the Idea, needs to be transferred to the corresponding Proposal if it is generated from that Idea.

I have attempted to capture these field values using Groovy scripts but have not succeeded so far. Additionally, I could not identify any native integration or effective way to transfer fields between Ideas and Proposals, or vice versa.
