Design Webflow Template with variable number of subsection

I currently have a website, with a cms collection(named manuals), which has a multi-reference field. The multi-reference field holds a lot of items from a second collection(named tasks).

The Problem is, if I use the Editor, i can’t change the field content of item of the second collection from inside the item of first collection. I’m searching for a way to access the access the items(purple fields in the picture) from this page.

Is there some kind of plugin or ohter way to do that?

In the following you see the Editor with an item of the first collection.

Thank you for your help.
