Enhance "draggable" attribute of components in order to allow excluding certain components when wildcard "*" is set for draggable components

Hi. I wish to enhance "draggable" attribute of components in order to allow excluding certain components when wildcard "*" is set for draggable components. For example, according to my case:

I need the "video" and "image" component to be draggable on every component, except the "my_custom_component". My suggestion is to add a new attribute "draggable_excluding" or to enable two fields in "draggable" attribute as an object: draggable: { components: c, //c typeof string or array exclude: e //e typeof string or array }

Thanks in advance.
