Remove list flascard from a rem

Hi !
I would like to know if there is a convenient way to remove a list flashcard from a rem without having to delete it all the item listed and rewrite them back.

Thank you for your help

Setect all children (bullets with black vertical line)
Search for card in Omnibar (open it with Ctrl + /)

TIPS : You can change any type of rems’ format with Omnibar

Thank you for your help ! That was very nice !
