Inline input groups

You must have filled out a form a lot. Often, they have the ability to create lists of objects with multiple fields.

This suggestion is to allow geometry nodes for a group to specify auxiliary groups. It doesn't have to be new sockets. It suffices to have a node type that can refer to the group that is selected as such an element. For the group that owns such a node, the inline node's input sockets also appear in its render form. The main advantage in this would be that if one group can reuse itself, then this would mean that the user can make his own method of combining the result of this group. It's not a loop, it's just a tuning variant.

The best use case for this would be groups for operators. Since now the user could, in addition to creating his own group for this, also make optional groups for more detailed settings. Then their use will be included as a checkbox at the bottom of the menu.
