Edit in group

Any command that I can edit in group so that I don’t need to ungroup ?

Dear @Chun_Ron_Li
you can sub-select objects inside a group:

PC:
ctrl+shift+left-click

MAC:
cmd/apple + shift + left click

Hi -
And in addition to what Tom said, you can remove a single object from a group and add an object to an existing group.
