Hi @contactcreatives thanks for the question!
Are you able to post a snippet of the custom component code here so I could see how you have it set up? It sounds to me like you want to achieve something like what is outlined in this forum post: How to Add Dynamic Editing Regions to Custom Components
Check it out and see if that works for you. If not, please feel free to post code snippets here and we can try to take a deeper look!
